The properties of coarse aggregates have a major influence on the strength of concrete. One of the important necessities in order to produce HSC is the high strength of aggregate particles.

Get Pricemany factors which control concrete compressive strength. Concrete mix proportioning, aggregate quality, aggregate gradation, type of cement, mixing and placing method, concrete curing and curing temperature and the most important one is the water cement ratio. Water cement (W/C) ratio has a critical impact on concrete strength characteristic.

Get Priceoveremphasized. The influence of aggregate on concrete strength is not generally appreci-ated. Usually, the aggregate strength is not the relevant factor in normal strength concrete as with the exception of lightweight aggregates, the aggregate particle is several times stronger than the matrix and the interfacial transition zone in concrete.

Get Pricecompressive strength of concrete decreased as the percentage replacement increased but replacement of sand by sawdust produced a higher percentage reduction in compressive strength than in density. Sawdust can potentially be used as aggregate in the production of both non-structural lightweight concrete and structural concrete.

Get PriceIn grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate. Voids in the coarse aggregate are filled in by sand and voids in the sand are filled in by cement. Mix that occupies the least volume is the densest and will produce the best results.
