pebbles properties in concrete

ANALYSIS OF PROPERTIES OF CONCRETE USING

This gives better results hence we can use clay soil aggregate as course aggregate where temperature of concrete plays an important role. Using expanded clay pebbles as fine aggregates increases the aesthetic appearance, so this can be used in manufacturing ceramics, tiles and crockeries.

Properties of Concrete - EzineArticles

The strength of the aggregate used also determines the strength of concrete. If rough pieces of rock are used to make concrete, the resulting concrete is stronger than that produced from smooth pebbles. The materials used should not increase the quantity of bondage as this weakens concrete. This is what happens when smooth pebbles are used.

The Effect of Aggregate Properties on Concrete

2000-3-30  Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to80 percent of the volume and 70 to 85 percent of the weight of concrete. Although aggregate is considered inert filler, it is a necessary componentthat defines the concrete’s thermal and elastic properties ...

Study on Mechanical Character of C50 Box-beam

Abstract: The mechanical character of natural Pebbles concrete and crushed stone concrete is studied in this study. The results show that compared with the aggregate concrete, the W/B can reduce the crushed stone concrete to a certain extent. For the C50 box beam concrete, the water cement will decrease by
