The present research study focused on the high early strength concrete properties that can be produced with large replacement of cement by fly ash. also, the effects of adding fibres on the compressive strength gain and early age strength gain properties are determined. tests were conducted on different high strength concrete specimens, where fly ash was substituted for cement.
Keywords: aggregate size, concrete workability, compressive strength, granite chippings, concrete properties. introduction . concrete is a miure oxt f water, cement or binder and aggregates and is a commonly used material for construction. (barritt, 1984). the strength of concrete depends on aggregate type, size and.
Strength of concrete is also affected by the properties of coarse aggregates besides watercement ratio and other properties. the lower the water to cement ratio, the more the effect of coarse aggregates on the strength of concrete. undesired properties of coarse aggregate may affect the strength, durability, and performance of concrete negatively.
Mixture proportions of concrete. the normal concrete was prepared based on water cement ratio of 0.50 and a cement content of 340kgm 3 to obtain a compressive strength greater than 20nmm 2 at 28 days (immersion method of curing). quartzite sand was used with a quantity of 33.33 of total aggregates by weight.
On. strength performance remains the most important property of structural concrete, from an engineering viewpoint. the relation between concrete composition and mechanical properties has long been a matter of research interest , , , .the strength of the concrete is determined by the characteristics of the mortar, coarse aggregate, and the interface.
This paper studied the effect of aggregate properties on the crushing strength of concrete. in order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test. and the test results show that concrete made from black stone has the highest workability followed by shingles stone amp; brick khoa of aggregates.
Ratio) performed well in the production of higher strength concrete in comparison to other aggregates (sadiq et al., 2019). it has been established that aggregates have significant effect on other mechanical properties of concrete, apart from basic properties related to compressive strength. the effect of aggregate size on.
