Quality Control

Introduction:Testing the quality of building material is very necessary at the site before it is ready to be used as a construction material. The material which is used on site suffers from many different environmental conditions (moisture conditions and temperature conditions) then the material tested in the laboratory as compared to the control conditions of laboratory. The material available near the site for example the water has to be tested for its construction requirements as it may affect the quality of construction. The water used must not have high chlorine content.

Since the moisture content of sand varies continuously depending upon different weather conditions so its moisture content has to be check regularly and necessary correction has to be implanted and proper quantity of sand and aggregate can be used to achieve the desired standard of strength.

Admixtures are substances used in small quantity to increase the workability of the concrete for the given water cement ratio without affecting the strength of the concrete. Admixtures used at the site are Sikament170PL4.

Water proofing of walls and floors are necessary to prevent them from dampness and destruction of steel in reinforcement due to rusting and to prevent subsequent leakages and even in worst cases failure of complete structure.

According to the material available at the site before starting of the construction proper mix design is done and is estimated that what moisture content will amount to what strength in concrete and a regular check is made by testing the concrete while construction and proper correction is made if necessary.

Fundamentals of Quality Controls: Water proofing of walls and floors are done by layering the walls and floors by

water proofing compound DR. FIXIT PIDECRETE MPB in 1:1 ratio by cement of thickness about 1 mm.

The steel used for construction purpose is Fe 500 TMT (Thermo-Mechanically Treated) bars.

The grade of concrete used for construction purpose varies from M-25 to M-40 grade concrete.

Flakiness and elongation index of aggregate should be below 35%. Aggregate are tested for their strength by aggregate crushing and aggregate

impact test on site. Maximum size of aggregate used at site is 20 mm and minimum is 10 mm. The test are made according to IS – 2386 Part (I-VIII).

Cubes are casted and check for their strength by checking their 7 days and 20 days compressive strength.

Non-destructive tests (like ultrasonic test etc.) are done on concrete if the concrete fails to achieve the desired strength after 28 days to determine the cause of such weak strength (due to honey-bee structure, etc.)

Admixture used is 0.6% by weight of cement.

Quality Control at Site:Quality of the various materials utilized in the field is tested at the site itself. A

separate room for the testing of the various materials has been provided at the site office. A cube testing machine, a hot-air oven and a sieve shaker is present in the quality control room. At present only the cube test and the slump test are being conducted, as no other material except for concrete is being used at the site. Though the cube test is not of much significance here, it is being conducted at the site to assure the quality of the mix. Since the concrete is being supplied by the company the cube test of the concrete becomes all the more significant. Usually 6 cubes are tested when light concreting is being carried out and a minimum of 12 cubes are tested when heavy concreting is being carried out. The samples of concrete are randomly taken from the trucks that bring in the ready mix concrete. The number of cubes that are tested depends upon the client also. The cube test is usually conducted in the presence of the client. The slump test is conducted in the field itself. It is carried out to determine the workability of the mix. The acceptability limits of the slump of the concrete is slightly increased after taking into consideration the weather conditions prevalent in the region i.e. hot and humid weather conditions. The various other tests will be conducted once the brickwork, plastering, etc. starts. Bricks, sand, etc. will not be supplied by the client hence the testing of these materials becomes a necessity as the usage of low of the failure will have to be borne by the company. Quality materials may lead to failure and the whole responsibility. The bricks will be tested using the hot-air oven. The sieve analysis will be conducted to test the quality of the sand that is being used. The quality of cement that is being used is determined by finding the initial setting time and the final setting time of the cement.

Tests Conducted on Soil: Sand Replacement Method. Core Cutter Method. Proctor Test. Vicat’s apparatus Test. Pycnometer Test.

Test on Aggregate: Sieve analyses. Flakiness and elongation test. Aggregate Impact test. Aggregate Crushing test.

Test on Concrete: Compressive strength test.

Case Study and Suggestions

Wastage of dowel bars: Case: These are to be provided as reinforcement for the supporting walls for the

LIFT (ELEVATOR). But the LIFT that has to be incorporated, its design is not yet finalized. The dowel bars are long enough to provide reinforcement for any size of the wall, but it will be used only as per the requirement when the design will be finalized and the remaining part will be removed as a waste, or might be removed completely moreover it is getting corroded, as left like that since long.

Suggestion: The design of the LIFT must have been made prior to the construction work, so that the wastage of the bars would have been checked. And if on a whole the full site is considered, this wastage can be a big bother.

Unused Passenger Hoist: Case: A Passenger Hoist is installed in front of a Block for lifting man, small and

light weighed materials/tools/etc, is very costly and something more than the required one. Operation of this lift a very expensive, because power requirement is too high than tradition of this segment. Presently at the site, there is no means to provide such expensive equipments.

Suggestion: If the cost of the generator was unaffordable, then such an expensive lift should not have been bought. Now, it can be shifted to any other project of the company where it can be used efficiently.

Unused Spare Area: Case: A considerable space is left beside flats of Block-1 and similar blocks as

spare area, while the same is not the case with the other blocks. This space is of no use as in particular.

Suggestion: This would be taken as an architectural imperfection as of which can be included in the boundary area of the flat, which thereby would have increased the carpet area of the flat.

Facilities Provided to the Workers: Case: For any type of manual work to be carried out effectively and efficiently the

most important factor is ‘Mental strength’. Human mind become monotonous and tedious doing a same work repeatedly and thus the efficiency decreases. This definitely increases the tenure for completion of the project.

Suggestion : When dealing in lakhs and crores, what a few thousands of rupees will matter, which if invested in fact will be a blessing in disguise. What could have been done is, a film projector can be provided which is not very costly, on which the workers during night time can see movies/films and get freshen up. This can be very beneficial for many aspects. Their efficiency will grow and the company will be benefited. Moreover, with such a small facility, the company will be praised by their workers.

Quality Control Lab: Case : Quality control at site is provided in order to maintain a desired degree of

quality of construction material together with the protection of environment. It includes the quality of steel used, cement, bricks, aggregate, etc. which provides stability to any structure. A quality control lab should have a garden in front of it, which encourages and shows that the construction being done at site is environmental friendly and creates a good working environment.

There are certain tests that demand to be conducted in a control temperature. So the quality control must have a certain temperature-controlling device so that the tests are conducted in a proper manner.

Suggestion : There should be a garden in front of the lab and temperature-controlling device.

Public transport accessibility and transportation route: Case : The mode of transport and the way of transport to the construction site

should be quick and easiest so that the work can be started at the earliest without delays and is comfortable to the engineers and working people and they remain fresh and effective after coming at site.

The bus takes the engineers and workers from a place name ‘Chingrihatta’. From this place there are two possible routes to reach the site, the one is by the by-pass (short-route) and the other is a normal long route. The bus takes from the long route, as just after the flyover there is a sharp turn and the road is muddy over

there, which increases the chances of toppling of bus. This causes an additional 20 minutes more to reach the construction site that’s means the work could have started 20 minutes earlier besides this it causes a large inconvenience as there is a single bus running to the site and almost 50% people goes standing in bus.

Suggestion : Since the construction is a long-term work the company can repair the shortest route so that the working people can reach by spending less time in bus moreover it will add to the company economy by saving the cost to petrol consumption and attract the buyers by the mode of infrastructure to reach the place. Also by increasing the number of vehicles company can provide comfort to its workers so that their mind gives more productivity.

Water logging problem surrounding the batching plant: Case : It is always necessary to create a proper concrete base near the batching

plant so that the ingredients of concrete can be collected over that concrete base in a proper quantity; a concrete base helps in providing a platform to these materials and helps in proper utilization (less wastage) of the material.

At site although a concrete base was prepared but it was not proper, the nearby dirty sand come into the way of backhoe which get mixed up in the material and is carried up by the batching plant which led to the side depression during rainy season. This depression has creates the water logging problem at the backside of the batching plant and causes difficulty in movement of backhoe. Now every time whenever there is a rain water gets collects over there and a pump is used to remove the water which adds to the cost of construction project and also use of an extra manpower which could have been used at some other work.

Suggestion : The broken bricks, sand gravels and even the waste material generated during pile caps can fill up the place where the depression has been created.

Protection of reinforcement from corrosion Case : Steel is the heart of any R.C.C. building. It is the most important, costlier,

and is very prone to rusting and hence proper care of steel is very necessary. A

proper isolated place should be there to keep the steel where there is no moisture, also only the required quantity of steel should be present on site so that its managing could be done in a proper way. There were two major problems at site: Firstly, the steel was placed randomly at site in an open atmosphere that caused rusting of steel. Secondly, since phase 2 constructions have been stopped. The dowel bars that were protruded from columns are getting corroded in the open atmosphere. If such condition persists further then the strength of steel will be reduced to great strength and it couldn’t be used for further extension of building.

Suggestion : There should be a proper isolated structure free from moisture for the steel. The dowel bars should be coated with the anticorrosive material to prevent the steel from being corroded further. The basement which has been prepared can be used a storage space for steel.
