The effects of aggregate-to-cement A/C ratios and types of aggregates on the properties of pre-cast concrete blocks are evaluated in this study A/C ratios between three and six and three types of aggregates ie, natural crushed aggregate NCA , recycled crushed aggregate RCA and recycled crushed glass RCG were used in the experiments...
of ingredients of a concrete mix is in the terms of parts or ratios of cement, fine and coarse aggregat For eg, a concrete mix of proportions 1 2 4 means that cement, fine and coarse aggregate are in the ratio 1 2 4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate The proportions are...
The main parameters affecting the aggregate packing density are the shape and combined particle size distribution of the aggregates used in the mix Once the aggregate supply has been selected, the only parameter that the mix designer can manipulate is the fine/coarse aggregates ratio...
If the quantities of coarse aggregate, fine aggregate, cement and water are the same for both mixes, the mix with l l/2-inch aggregate will have greater slump and will probably bleed more , because its water-cement ratio will be lower However this increase in strength may not be significant because of other factors that affect strength ....
Effect of Coarse Aggregate on Strength of Concrete Coarse aggregate makes up about 75 of concrete by volume Strength of concrete is also affected by the properties of coarse aggregates besides water-cement ratio and other properti The lower the water to cement ratio, the more the effect of coarse aggregates on the strength of concrete...
