alternatives to natural sand and evaluate these alternatives for use in concrete production. Out of the many available alternatives, crushed stone sand has emerged as the most easily available material. This material is available at all the crushing units as a by-product during production of …

Alternative Materials for Coarse Aggregates. There are a number of materials available for the alternative for coarse aggregate in concrete.In concrete, we can alternate cement with reuse materials to reduce energy consumption. The list of wastes used in concrete can include fly ash, wood ash, blast furnace slag, or fumed silica. The partial replacement of coarse aggregate in concrete can …

With initial stock levels of forty million metric tons (mmt.) each of wheat and coarse grain and twenty mmt. of rice, buffer stock operations reduce the average st and ard deviation of ...

A Comparison Study in Partial Replacement of Coarse Aggregate with Coconut Shell in Concrete

Many studies have been conducted as alternative coarse aggregate to concrete [6 to 14]. The brief literature review of some of studies are as follows. Rahate et. al. [6] conducted experimental program to investigate characteristics of concrete using coconut shell by partial replacement of coarse aggregate.

So experts are desperately looking for a suitable alternative for coarse aggregate—the low cost and lightweight, which does not affect nature much. We have already started using M sand instead of river sand. The natural or synthetic lightweight aggregates make lightweight concrete. It is a low cost along with excellent durability.

High-density polyethylene can be added to concrete and sand as a feasible replacement for course aggregate. Research has shown that plastic bags that are tightly packed and then heated, shrink to a size that can easily be used in concrete. But as the name implies, the material is too ductile at full strength to support structural loads at ...

coarse aggregate or Date Seed or coarse aggregate/Date Seed) and 1:3:6 were investigated with water/cement ratio of 0.55, 0.60, 0.65 and 0.70 respectively so as to obtain the required w/c ratio for the actual mixes. W/c ratio of 0.6 was adopted for 1:2:4 mix and 0.65 for 1:3:6. Concrete mixes were properly mixed in a machine mixer for about six to
