| dc.description.sponsorship | In the recent time effort has been made to replace Portland Cement (PC) wholly, thus producing an alternative binder. This innovation could be due to environmental challenges attributed to the green-house gas emission coupled with energy intensity and consumption associated with PC production. The use of Rice Husk Ash (RHA) and Calcium Carbide Waste (CCW) as a binder in the production of mortar has revealed positive results with some drawbacks such as poor initial setting time (IST), final setting time (FST) and early strength gain. This study therefore target at inclusion of silica-Nano particle (SNP) and superplasticizer in RHA-CCW binder with a view to evaluate the influence of SNP inclusion of its performance characteristics. Silica-Nano Particles were extracted by chemical leaching of the RHA and so was the physical and chemical properties of the constituents materials determined before the assessment of the fresh properties of the binder paste. Mortar specimen were thereby made with 60:40 RHA CCW binder containing varied SNP contents (i.e. 0 to 5 % at 0.5 step increment) for 1:3 binder/sand mix of 0.5 W/B ratio. This was tested for compressive strength, water absorption and abrasion resistance at various curing ages in accordance with BS EN 196-1:2016 for Strength of cement and other established standards. The results shows mortar specimen of 60:40 RHA-CCW binder containing 3% SNP has the best performance in compressive strength (having 28 56 and 90 days values of 10.94, 13.50 and 15.75 N/mm2) representing an increase in strength 40, 63 and 80 % when compared to the RHA-CCW without SNP. 3% SNP addition in 60:40 RHA-CCW binder at 60/40 1:3 binder sand mortar, with 0.5W/B and 1.5% Superplasticizer by weight of binder was thereby recommended for masonry operations as it conforms to Class N of ASTM C270. | en_US |
