ITEM: Pre-coolingto control placement temperature of cement concretein the range of 18 to 21 C

at the concrete placement point by inundation of coarse aggregates and adding flaked ice as

part of mixing water including cost of all materials, machinery, labour etc., complete with all

leads and lifts.

DATA:Consider M-15 grade concrete using 80 mm down CA and 30-50 mm slump.

Requirement of materials per cum of concrete:

Cement : 210 kg

Fine aggregate : 575 kg

Coarse aggregate : 1490 kg

Water for W / C ratio of 0.6 for use of air entraining admixture : 126 kg

Daily concreting programme ( based on data in item - 13 ) : 500 cum

Hourly output of batching plant ( based on data in item-13 ) : 30 cum

Proposed temperature of concrete at placing point : between 18 & 21 deg C

Av. temperature of concrete at placing point considered for rate analysis : 19.5 deg C

Probable gain in temperature during conveying CC from BP to block : 2 to 3 deg C

Av gain in temperature during conveying CC considered for rate analysis : 2.5 deg C

Required temperature of concrete at batching plant ( 19.5 - 2.5 ) : 17 deg C

Precooling of aggregate is not considered. However, as coarse aggregate stocked in open area

is exposed to sunlight during day time spraying normal water over coarse aggregate heaps is

considered to keep the aggregate temperature at minimum possible level.Use of chilled water and flaked ice is considered for mixing concrete.

Material parameters considered / assumed for determining the quantity of ice flakes:

Weight of Cement ( Wc ) : 210 kg

Temperature of cement in silo ( Tc ) : 45 deg C

Specific heat of cement ( Cc ) : 0.25

Weight of Coarse aggregate ( Wa ) : 1490 kg

Temperature of wet CA in BP aggregate bins ( Ta ) : 25 deg C

Specific heat of coarse aggregate ( Ca ) : 0.22

6/21

DAM ALLIED WORKS

Free water in wet CA @ 2% ( 0.02 x 1490 ) ( Wam ) : 29.80 kg

Weight of Fine aggregate ( Ws ) : 575 kg

Temperature of FA in BP fine aggregate bin ( Ts ) : 27 deg C

Specific heat of fine aggregate ( Cs ) : 0.22

Free moisture in wet FA @ 1% ( 0.01 x 575 ) ( Wsm ) : 5.75 kg

Weight of Water including free moisture and ice flakes ( Ww ) : 126 kg

Temperature of chilled water in BP mixing water tank ( Tw ) : 5 deg C

Specific heat of normal / chilled water ( Cw ) : 1.00

Weight of ice flakes in kg ( Wi ) : to be determined

Temperature of ice flakes in ice elevator ( Ti ) : - 5 deg C

Specific heat of ice flakes ( Ci ) : 0.50

Latent heat in kilo calories ( kcal ) ( L ) : 80 kcal

Required temperature of concrete at batching plant ( T ) : 17 deg C

1.a Heat dissipated by Cement / CA / FA / free water in CA & FA :

Heat dissipated by Cement in kcal Wc x Cc ( Tc - T )

210 x 0.25 ( 45 - 17 ) say: 1470.00

Heat dissipated by Coarse aggregate in kcal Wa x Ca ( Ta - T )

1490 x 0.22 ( 25 - 17 ) say: 2625.00

Heat dissipated by Fine aggregate in kcal Ws x Cs ( Ts - T )

575 x 0.22 ( 27 - 17 ) say: 1265.00

Heat dissipated by free water in CA in kcal Wam x Cw ( Ta - T ) 29.80 x 1.00 ( 25 - 17 ) say: 240.00

Heat dissipated by moisture in FA in kcal Wsm x Cw ( Ts - T )

5.75 x 1.00 ( 27 - 17 ) say: 60.00

Total heat dissipated in kcal = 1470.00 + 2625.00 + 1265.00 + 240.00 + 60.00

= 5660.00 kcal

1.b Heat absorbed by Chilled water / Ice flakes :

Quantity of chilled mixing water = ( Ww - Wam - Wsm - Wi )

Heat absorbed by chilled mixing water in kcal = ( Ww-Wam-Wsm-Wi ) Cw ( T -Tw )

( 126 - 29.8 - 5.75 - Wi ) x 1.00 x ( 17 - 5 ) : 1085 - 12Wi

Heat absorbed by ice flakes in kcal = Wi x ( Cw x T - Ci x Ti + L )

= Wi x ( 1 x 17 - 0.5 x -5 + 80 ) : 99.5Wi kcal

Total heat absorbed by chilled water and ice flakes in kcal = 1085.00 - 12Wi + 99.5Wi

= ( 1085.00 + 87.5Wi )

1.c Quantity of ice required based on heat balance equation :

Total heat absorbed by chilled water and ice flakes = Total heat dissipated by other ingradients

1085.00 + 87.5Wi = 5660.00

87.5 Wi = 5660.00 - 1085.00

Weight of ice flake / cum of concrete ( 5660.00 - 1085.00 ) / 87.5 say : 53 kg

Quantity of ice required / day for 500 cum concrete ( 53 x 500 ) / 1000 : 26.5 tonnes

Consider pre-cooling of 500 cum concrete for rate analysis.


No materials required for pre-cooling of concrete.
