The Complete Guide to Crushed Stone and Gravel

Crushed stone: If you hear the generic "crushed stone" term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.

Boreholes were drilled to examine the depth of the crushed stones after soil improvement. One of the borehole logs is shown in Fig. 18.8.The stones were found to be present up to 9 m, in which the top 5 or 6 m was densely packed, whereas the remaining 4 or 5 m was embedded in clay.Below the crushed stone layer were a silty gravel layer and the weathered sandstone layer.

Water content - Wikipedia

Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, crops, or wood.Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials' porosity at saturation. It can be given on a volumetric or mass ...

Aggregates for Concrete

Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.

Section III: Surface Gravel

it is still common to process gravel simply by screening to a maximum top size.A great benefit is gained from processing the material by crushing. This means that a good percentage of the stone will be fractured in the crushing process.The broken stones will embed into the surface of a gravel road much better than rounded, natural-shaped stone.

how is limestone formed


Limestone is about 10% of the total volume of all sedimentary rocks. Crushed limestone and stepping stones can save runoff as well as provide a path to pass safely during wet seasons. Some carbonate dissolves in the water. Marble is also a carbonate rock that has been squeezed down and formed into a different material with heat and pressure. These organisms secrete shells made of …

Clay - Wikipedia

Clay is a type of fine-grained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour ...
