Aggregates for Concrete

natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel.

How to Process Sand

The primary magnetic separation is carried out to remove the waste iron from the aggregate. Crushing and sand-making. Firstly, use a vibrating feeder to feed the raw materials evenly. Then use a jaw crusher to crush them. The jaw crusher uses the movement of the jaw plate to crush the large aggregate of sand and gravel into smaller particles.Get price

Sand Extraction: 1. Introduction

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.Get price
