Sandaggregate ratio of normal concrete depends on watercement ratio and the maximum grain sie of coarse aggregate. However in fact sandaggregate ratio is not only dependent on above factor but also is affected by cement variety. In this paper considering this effect we brought up Eq.4.

Details20191124 Effect of Aggregate Cement Ratio on Workability of Concrete. Aggregate cement ratio is the ratio of weights of aggregate to the weight of cement. If this ratio is more that implies aggregates are more and cement is less and if this ratio is less that implies weight of aggregate is less and weight of cement is more relatively.

Details20191124 In this post I shall discuss maximum aggregate sie that can be used in design. Large maximum sies of aggregates produce less voids than smaller sies. Hence concretes with the largersied aggregates require less mortar per unit volume of concrete and of coarse it is the mortar which contains the most expensive ingredient cement.
Details2000330 The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material aggregate and water. Aggregate is commonly considered inert filler which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.
DetailsIn general if the watercement ratio is chosen correctly a wide range in grading can be used without a major effect on strength. When gapgraded aggregate are specified certain particle sies of aggregate are omitted from the sie continuum. Gapgraded aggregate are used to obtain uniform textures in exposed aggregate concrete.
DetailsConcrete is a predominant component among all construction materials. Today the enhancement in civil engineering and construction technology enables us to use a concrete mix ratio that suits the purpose of all structures individually.

For watercement ratios under 0.3 disproportionately high increases in the compressive strength can be achieved with very small reductions in watercement ratio. A significant improvement in the
DetailsConcrete mix ratios are usually in the form of cement Sand Aggregate. For example if the concrete mix ratio of M20 concrete is 11.53 then 1 part of cement 1.5 part of sand and 3 part of aggregate in volume should be taken to produce concrete.

DetailsThe effects of aggregatetocement AC ratios and types of aggregates on the properties of precast concrete blocks are evaluated in this study. AC ratios between three and six and three types of aggregates i.e. natural crushed aggregate NCA recycled crushed aggregate RCA and recycled crushed glass RCG were used in the experiments.
DetailsIn order to produce concrete with a lower watertocement ratio chemical admixtures can reduce the required amount of mixing water and still obtain the desired fresh properties to facilitate the placement and consolidation of the concrete. One of the key parameters in producing highstrength concrete is the use of a low wc ratio.
DetailsMix design is a process of determining the right quality materials and their relative proportions to prepare concrete of desired properties like workability strength setting time and durability. While following a mix design is advised to optimise the material consumption it is not possible at site to always come up with Mix design. Nominal mix
