Properties of Concrete with Coconut Shells as Aggregate ...

Abstract––Properties of concrete with coconut shells (CS) as aggregate replacement were studied. Control concrete with normal aggregate and CS concrete with 10 20% coarse aggregate replacement with CS were made. Two mixes with CS and fly ash were also made to investigate fly ash effect on CS replaced concretes.

High strength concrete properties, admixture, and mix ...

Concrete is a mixture of cement, water, coarse and fine aggregates with or without chemical and mineral admixtures. As aggregate covers 75 percent of the volume of concrete, for HSC, highstrength wellgraded aggregate is essential. The presence of different sizes of aggregate (wellgraded) in appropriate proportions is important to reduce void.

AlkaliAggregate Reaction

AlkaliAggregate Reaction

AlkaliAggregate Reaction. In most concrete, aggregates are more or less chemically inert. However, some aggregates react with the alkali hydroxides in concrete, causing expansion and cracking over a period of many years. This alkaliaggregate reaction has two forms: alkalisilica reaction (ASR) and alkalicarbonate reaction (ACR).

Generally, aggregate properties affect not only the concrete mixture proportions but also the behavior of fresh and hardened concrete. Due to considerable overlap between the two, it is more appropriate to divide the study of aggregate properties into three egories that are based on microstructural and processing factors.

 · When the concrete is first mixed it is like 'bread dough'. It is soft and can be worked or moulded into different shapes. In this state concrete is called PLASTIC. Concrete is plastic during placing and compaction. The most important properties of plastic concrete are workability and cohesiveness. A worker will sink into plastic concrete.
