Mechanical Characterization of Lightweight ed Concrete

ed concrete shows excellent physical characteristics such as low self weight, relatively high strength and superb thermal and acoustic insulation properties. It allows for minimal consumption of aggregate, and by replacement of a part of cement by fly ash, it contributes to the waste utilization principles. For many years, the application of ed …

Water content

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 ...

Acid mine drainage

Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually …

What Is Coarse Aggregate | Properties of Coarse Aggregate

B) Classification of Aggregates Based on Grain Size Depending upon the size of the aggregate they can be classified into two categories as fine aggregates and coarse aggregates.. 1. Fine Aggregates. The size of the fine aggregates is lesser than 4.75 mm.That is aggregates particles that passed through 4.75 mm. fine aggregates include things such as …

Enhancing the microstructure and surface texture of recycled …

1. Introduction. Accelerated carbonation has been reckoned as a useful method for densifying porous cementitious materials,, .The densification of microstructure is attributed to the volume expansion (by a factor of ~1.1–1.4) of calcium hydroxide (CH) upon its conversion to calcium carbonate (Cc, CaCO 3) .Hence, considering the residual CH contained in recycled concrete …

Alkali-Aggregate Reaction

In most concrete, aggregates are more or less chemically inert. However, some aggregates react with the alkali hydroxides in concrete, causing expansion and cracking over a period of many years. This alkali-aggregate reaction has two forms: alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR).

Polymers

Many polymeric materials having chain-like structures similar to polyethylene are known. Polymers formed by a straightforward linking together of monomer units, with no loss or gain of material, are called addition polymers or chain-growth polymers.A listing of some important addition polymers and their monomer precursors is presented in the following table.
