Effect of Partial Replacement of Cement by SCBA on Workability of Concrete

Nidhi Nagpal, Dr. A K Saxena

Abstract: All over the world various researches are being carried out by focusing on consumption of industrial or Agricultural waste as a replacement of cement in concrete. However utilization of these waste proves to be economical, and also result in foreign exchange earnings as well as environmental pollution is reduced to some extent. Various wastes from industries, like blast furnace slag, fly ash and silica fume are now days commonly used as cement replacement materials. In the present study and work the sugarcane bagasse ash (SCBA) is used as alternate binding material. This has resulted in saving in cement consumption almost equivalent to the alternative binding material (SCBA) used in concrete. The bagasse ash used for this work is obtained from Sant Tukaram factory (Pune) which is grinded and sieved through sieve of size 150 micron and passing out fraction is used in concrete as a partial replacement of cement in the ratio of 0 %, 5 %, 10 %, 15 %, 20 % and 25 % by weight of the cement. OPC 53 grade cement is used in the study. The effect of replacement of cement by bagasse ash on properties like workability for fresh concrete is determined. It is observed that by reducing w/c ratio by approx.0.01 for every 5 % additional replacement of cement by SCBA the desired value i. e.75 mm slump value (average) is obtained. During research work 0.5 % super plasticizer, Fosroc conplast SP500 (a high range water reducer, based on sulphonated naphthalene polymer) by the weight of cement is also used.

Keywords: Sugar-cane bagasse ash SCBA, cement replacement, compressive strength, workability and durability
