The effect of natural sand composition on concrete ...

Jun 01, 2016  However, natural sand has a smooth, rounded surface texture that greatly reduces the interlocking properties of the concrete, reducing its strength properties , , , , . The aim of this study is to evaluate the effects of the composition of natural sand of different origins on concrete strength.

The effect of natural sand composition on concrete ...

Natural sands vary in composition and may cause different concrete strength. We highlight some mechanical aspects regarding the use of sand from different origins. Sands containing smectite-type clays cause lower concrete strength. Na 2 O content of sands is important for predicting the strength of concrete.

Properties of Concrete by Replacement of Natural Sand with ...

The advantage of natural sand is that the particles are cubical or rounded with smooth surface texture. The grading of natural sand is always not ideal. It depends upon place to place. Being cubical, rounded and smooth textured, it gives good workability. One of the important ingredients of conventional concrete is natural sand or river sand.

Dec 01, 2016  This research consists of incorporating the crushed sand (CS) in the composition of a concrete and studies the effect of its gradual replacement by the sand dune (SD) on sustainability of high performance concrete (HPC) in aggressive environments. The experimental study shows that the parameters of workability of HPC are improved when the CS is partially replaced by the SD (#x3c;2/3).

Aggregates - Cement

Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.

Sand Extraction: 1. Introduction - GreenFacts

Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world’s use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.
