Combined Use of Accelerators and Stone Slurry Powder in Cement Mortar
Abstract Accelerating admixtures have an important role in the construction industries to speed up the work by reducing setting time. Portland cement is an important ingredient in the mortar and concrete production. Large amount of CO2 is emitted during the manufacturing of cement. To minimize the CO2 emission up to some extent; industrial by-products can be utilised in concrete as replacement of cement. The stone slurry powder from stone industries has been used as replacement of cement in the present study. Calcium nitrate (1%), triethanolamine (0.025% and 0.1%) as additive and stone slurry powder (5%, 7.5% and 10%) as a replacement of cement was used. Consistency, setting time of cement paste; and compressive strength of the mortar using these materials was studied experimentally. Results showed that consistency increased; but, setting time of the cement paste decreased in comparison to the control mix. Calcium nitrate and stone slurry powder increased the compressive strength while TEA reduced the compressive strength of the cement mortar in comparison to control mix.
