Posted on July 18, 2019. Concrete is a mixture of cement, gravel, sand, water and a range of aggregates. With about 10 billion tons of concrete produced every year, it is the most consumed substance in the world, second only to water.. It is also the world's most widely used material for construction – from bridges to large buildings, concrete forms the very foundation of our infrastructure.
Insulating concrete forms, or ICFs, are forms used to hold fresh concrete that remain in place permanently to provide insulation for the structure they enclose. Their history dates back to after World War II, when blocks of treated wood fibers held together by cement were used in Switzerland. In the 1940s and 1950s, chemical companies developed ...
If you want to set up a new industry, you have to know the business, project report with its feasibility, i.e. will it be profitable or not. For this purpose you will need research the market of the product you want to produce, the availability of raw materials, cost of raw materials, cost of utilities and the cost of finished goods in the long run.
Foam concrete can be designed to have any density within the dry density range of 300–1850 kg/m3. In this investigation two foam concrete mixtures are produced with and without sand and attempts have been made for selecting the proportions of foam concrete mix for the target plastic density of …

Cellular Light Weight Concrete (CLC) is a version of lightweight concrete that is produced like normal concrete under ambient conditions. It is produced by initially making slurry of Cement, Fly Ash, and Water which is further mixed with the addition of pre-formed stable foam in a blender concrete mixer under ambient conditions.

This research report is prepared to show the activities and progress of the lightweight concrete research project. The performance of aerated lightweight concrete such as compressive strength tests, water absorption and density and supplementary tests and comparisons made with other types of lightweight concrete were carried out.
Autoclaved aerated concrete (AAC) block is a building material made of Portland cement, fine aggregates (fly ash or sand), water and an expansion agent in an autoclaving process heated under pressure which results in the production of air voids in the material, making it less dense, easy to cut/mould and better insulating

project located at a high school in Encinitas, CA. The Geofoam was installed under a stairway that connects to a structural retaining wall. The concrete formwork was connected directly to the foam and the stairs were poured in place onsite. The foam acted as the on-grade material, so the concrete stairs did not have to be self-supporting.

Foam concrete is a type of lightweight concrete that is manufactured from cement, sand or fly ash, water, and the foam. Foam concrete is in the form of foamed grout or foamed mortar. Foam concrete can be defined as a cementitious material that consists of minimum 20 percent of foam, that is mechanically entrained into the plastic mortar.
