What is the proportion of cement constituents (that is limestone and clay) that are mixed together during production? ... addiditives like silica sand, bauxite, iron ore or other materials ...
er limestone definitely has grain size. If you can't see the grainsize it's because you're looking at the (most common) mudgrade version. However, you can absolutely get sand, gravel and cobblegrade limestones at various places around reefs for example. And what's an oolitic limestone if not gravelgrade limestone?
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. Shale is a finegrained sedimentary rock which is formed by the compaction of silt and claysize mineral particles. These rocks are composed of many distinct minerals.
Definition of "limestone": colorless or white crystalline compound, CaCO3, occurring naturally as chalk,limestone, marble, Caliche, and other forms; "Limestone" is also used in a wide variety of manufactured products including commercial chalk, medicines, and dentifrices.
Clay is by far the smallest particles recognized in mudrocks. Most materials in nature are clay minerals, [clarification needed] but quartz, feldspar, iron oxides, and carbonates can weather to sizes of a typical clay mineral. For a size comparison, a claysized particle is 1/1000 the size of a sand grain.
Many types of crushed stone: Crushed stone is not a "standardized commodity." It is made by mining one of several types of rock such as limestone, granite, trap rock, scoria, basalt, dolomite, or sandstone; crushing the rock; and then screening the crushed rock to sizes .
Some limestones form from the cementation of sand and / or mud by calcite ( clastic limestone), and these often have the appearance of sandstone or mudstone. As calcite is the principle mineral component of limestone, it will fizz in dilute hydrochloric acid.
Sand and Sandstone. Sand is loose unconsolidated material having particle size between silt and pebbles (1/16 to 2mm). When held together by chemical cement or by clay, they are called sandstone. Sandstone results from the breaking down or weathering of older rocks and from the transportation and sorting of rock fragments by water or by wind.
Sep 12, 2009· Limestone is common here. Marl is the clay we have in some lower areas. A friend had a dirt driveway with a similar problem so we mixed cement and sand in the soup. It did harden and remains firm till this day. The cement bags were damaged marked down home depot stock. The sand came from another part of the lot.

Particle size, also called grain size, means the diameter of individual grains of sediment, or the lithified particles in clastic term may also be used for other granular materials.
includes viruses, small bacteria, metallurgical fumes, soot, oil smoke, tobacco smoke, clay, and fumes; Hazardous Dust Particles. Smaller dust particles can be hazardous for humans. In many jurisdictions dust fractions at specified particle sizes in working environments are required to be measured. Inhalable Dust
