Concrete is "the single most widely used material in the world," according to the Royal Society of Chemistry, "and it has a carbon footprint to match." In fact, the society notes that making concrete is responsible for between 5 and 7 percent of all annual anthropogenic global carbon dioxide production. (Anthropogenic refers to humankind's ...
Concrete A composite material made with chemicals, water, minerals, gravel, crushed rocks and sand. Concrete production emits significant amounts of carbon dioxide. However, in theory concrete could be used to sequester carbon. Plaster A material that is similar to concrete for use in interiors. Often made from gypsum, lime or cement.
They are the standard sized rectangular hollow blocks made of cast concrete of high or low density. For high-density blocks, Portland cement and aggregate, usually sand and fine gravel are used as a raw material. For low density blocks, industrial wastes, such as fly ash or bottom ash are used as the primary raw materials and are often called cinder blocks /breeze blocks in different parts of ...

The maximum tensile strength of concrete has been found of the order of 42.0 kg/cm 2. Some researchers have observed that the type of coarse aggregate has a greater relative effect on tensile strength than on compressive strength. Generally for concrete quality control, tensile test is never made.
That is true in many western countries. One will be amazed to see that pros that the baled straw gas over conventional building materials. Whether it's sustaining high temperatures or the durability. The houses made of baled straw have high insulation values that go up to R-35.Higher is the R value, higher is the insulation.

Wood, a natural composite, is a combination of cellulose or wood fibers and a substance called lignin. The fibers give wood its strength; lignin is the matrix or natural glue that binds and stabilizes them. Other composites are synthetic (man-made). Plywood is a man-made composite that combines natural and synthetic materials.
Classification of Modern concrete: Today, concrete is the most widely used manmade material and Concrete are classified into different types: 1. According to binding material used in concrete. 1. Cement concrete. 2. lime concrete. 2. According to design of concrete. 1. Plain cement concrete. 2. Reinforced cement concrete(RCC). 3.

Natural man made fibre (A) Cellulosic fibres Cellulose is one of many polymers found in nature. Wood, paper, and cotton all contain cellulose. Cellulose is an excellent fiber. Cellulose is made of repeat units of the monomer glucose. The three types of regenerated cellulosic fibres are rayon, acetate and triacetate
It became more or less a poor man's flooring. Now it is getting back its glory. The technique of using coloured cement for flooring is found in other parts of India too, such as the Chettinad tiles. In Bangalore too, there were many old buildings made with oxide floors. Even carpet like patterns are embossed in the floor using different colours.
