“…W zależności od stopnia zastąpienia kruszywa drobnego piaskiem kruszonym, odpowiednio zmienia się również wytrzymałość na ściskanie (3). Oprócz składników i proporcji mieszanki, rozmieszczenie ziaren kruszywa w różnych warunkach fi zycznych -mokre i suche, wpływa ogólnie na wytrzymałość betonu ( 4).…”

The growing demand for high strength concrete [HSC] in the construction industry increases the usage of cement, resulting in environmental issues. Recent studies are showing that the utilization of cementitious materials in concrete can effectively reduce the volume of cement. In the present study, ternary blended combinations were prepared using cement, silica fume, and fly ash to attain the HSC. Here, cement was partially replaced by silica fume [2.5, 5, 7.5, and 10%] and fly ash [5, 10, and 15%], respectively. Mini slump cone test was conducted to identify the compatibility of cement paste with polycarboxylate ether [PCE] based superplasticizer. The packing density of aggregates was calculated to reduce the voids and improve the particle distribution in HSC. An experimental investigation was carried out, and the ultimate compressive strength was obtained as 71.55 MPa at 28 days of curing. Multi linear regression analysis was conducted to simulate the mix design for aiding the prediction of compressive strength of the HSC.

“…Depending on the replacement level of fi ne aggregates with M--Sand [Manufactured Sand] the compressive strength also varies respectively (3). Apart from the ingredients and mix proportions, the distribution of the aggregates in different physical conditions [wet and dry] generally affects the strength of concrete ( 4).…”
