Effects of combined aggregate gradation on the

Aggregate gradation particle size distribution is a very important part of concrete production hence the need to combine coarse aggregate with fine aggregate in its simplest form An improperly graded aggregate structure can have undesirable effects on the properties of concrete as it can produce weak stiff or porous concretes In this research the properties of concrete in terms of

Predictive model for compressive strength of concrete made

The objective of the study is to replace coarse natural aggregate with recycled concrete coarse aggregate RCCA for concrete production in order to determine the compressive strength of such concrete for different percentages of partial replacement using different watercement ratios Thereafter develop a predictive model for the compressive strength using different percentages of partial
