14.4 Workmanship :-
14.4.1 Plain cement Concrete Flooring :-
Generally workmanship shall conform to IS 2571 code of practice for – laying in-situ concrete
floors. If the floor finish is to be laid over consolidated ground or a layer of hard core, cement
concrete of proportion 1:4:8 or 1:5:10 shall be poured as a base layer to the thickness indicated
on the drawings. In the case of structural slabs, the slab itself will form the required base.
The area requiring finish shall be divided into suitable panels so as to reduce the risk of
cracking. No dimension of a panel shall exceed 4min case of floor finish laid monolithically
with base concrete and 2m in case of floor finish laid separately on a hardened base length of a
panel shall not exceed 1 ½ its breadth.
Paneling shall be done by fixing timber or steel strips of depth equal to the combined thickness
of base concrete and topping. Before being fixed in position these strips shall be coated with a
thickness coat of time wash. Flooring shall be laid in alternative panels, the intermediate
panels being filled in after one of to days. However, if glass or aluminum strips are specified
for effective separation of panels, the base concrete and toping may be laid simultaneously in
all the panels.
Floor finish laid monolithically with base concrete :-
The sub base shall be properly wetted and divided into panels. The base concrete shall be
poured and tamped and screened to levels suitable to accommodate the topping and given the
desired slope. The surface shall be left rough to provide bond with the topping.
On the green surface of the base concrete topping shall be placed in position as soon as the
base has stiffened enough to allow workmen to tread over it by placing planks. The mix for the
topping shall be as shown in drawing and as stiff as possibly consistent with workability so as
to prevent accumulation of excess water on ???? should any water rise to surface during
compaction and screening, it shall be mopped up. The topping shall then the floated with the
wooden float to under the surface.
Floor finish laid separately on hardened concrete base.:-
The sub base shall be properly wetted and the base concrete laid, if possible over the whole
area at a stretch. The surface shall be left rough to provide adequate bond for the topping by
wire brushing two to three hours after its laying.
Before the topping is laid., the surface of the base shall be thoroughly cleaned of loose
materials, dirt and laitance by wire brushing. Where this is not possible, chipping or hacking
shall be done. The surface shall be soaked with water for 12 hours before laying the topping.
The surplus water shall be mopped up, cement slurry spread and then the concrete for the
topping deposited in suitably divided panels. The mix for the topping shall be as indicated in
drawing and as stiff as possible consistent with workability so as to prevent accumulation of
excess water laitance. After thorough consolidation the topping shall be struck off level and
surface floated with a wooden float. Is shall be tested with a straight edge and mason`s spirit
level to detect any inequalities and may undulations found shall be made good immediately.
14.5 Laying toppings in two layers. :-
Where it has been specified that the topping is to be laid in two layers to obtain very smooth
and dense finish, the base concrete and under-layer of topping shall be laid as above with the
exception that the surface of the finished smooth but left rough after tamping and leveling.
The top 15mm thick wearing of mix1:2 to 3 cement concrete of consistency stiffer than that of
under-layer of concrete shall then immediately laid over the rough but green surface of under-
layer and thoroughly temped, struck off level and the surface floated with the wooden float.
The surface shall then be tested with a straight edge and mason`s spirit level to detect any
undulations. If any these shall be made good and then the surface finished smooth as under.
116
14.6 Finishing the surfaces :
After the concrete has slightly hardened it shall be finished by trowelling or floating. Finishing
operations shall start shortly after the compaction of concrete and shall be spread over a period
of one to six hours depending upon temperature and atmospheric conditions. The surface shall
be trowelled three times at intervals so as to produce a uniform and hard surface. Immediately
after laying only just sufficient trowelling shall be done to give a level surface. Sometime after
the first trowelling, the duration being guided by temperature and rate of setting of cement, the
surface shall be retrowelled to close any pores in the surface and to draw out and mop up any
excess water in concrete or laitance. The final trowelling shall be done well before the
concrete has become too hard but at such a time that considerable pressure is required to make
any impression on the surface. Trowelling of a dry cement mix on the surface shall not be
permitted.
14.7 Curing
As soon as the surface has hardened beyond damage, it shall be kept continually moist for at
least 15 days by impounding water on it.
14.8 Polishing
The floor shall be polished with machine eight weeks after laying when the floor is
sufficiently matured by expert trained polishers. The floor shall than be sprinkled with zine or
tin oxide and rubbed hard with rags. The final polish shall be done with wax or with patent
polish.
14.9 Coloured Cement Concrete Flooring
Where coloured finish is finish is indicated, the top shall be finished with coloured cement as
specified. If coloured cement is not available, the pigment shall be mixed in the proportion,
one part of pigment with three parts of cement.
117
The colouring material and cement shall first be mixed dry. Special attention shall be paid to
the mixing of colour, which should be screened twice with a final screen and again through
final muslin before use. All the colour required for one room shall be mixed in one lot. For red
colour the mixture shall consist of one part of iron oxide to three parts of cement. For green
the colour mixture shall consist of one part of chromium oxide to 3 parts of cement. After dry
mixing, the minimum quantity of water required for workability shall be added gradually until
a paste of the required consistency is obtained. Dry colour shall not be used to finish the
surface of coloured concrete floor. Coloured paste shall be applied with wooden floating
boards and English trowels. 0.06 cu.m. of colour mixture shall be used for 10 sq.m. of surface.
Any cracks, ruts, disfiguration or discolouring of surface shall be made good without extra
charge. The finished portion of the floor shall be kept wet for at least 15 days.
Coloured concrete shall be polished with Nos. 1, 2 and 3 polishing stones. After rubbing with
these stones, the surface shall be sprinkled with zinc or tin oxide and rubbed hard with rags.
The final polish shall be done with wax or with patent polish. For light colours, celluloid
trowels made by fixing a sheet of celluloid on a wooden trowel may be used.

water. Thereafter it shall be evenly and uniformly covered with a coating of lime mortar about
20mm thick before the cushioning mortar has hardened, the back of each tiles to be fixed shall
be covered with a thin layer of neat cement paste and te tile shall be gently tapped against the
wall with a wooden mallet. The fixing shall be done from the bottom of the wall upwards.
Each tile shall be fixed as close as possible to the one adjoining, and any difference in the
thickness of the tiles shall be evened out in the cushioning mortar or cement paste so that all
he tile faces are set in conformity with one another.
Skirting and ado shall be ground and polished just as for floor work but by machine suitable
