2.3 Production of concrete using constituent materials Concrete cubes of size 100mm x 100mm x 100mm were produced using the six (6) mix proportion as presented in table 1, and cured for 90days to determine the compressive strength of the concrete before and after heating. The water-cement used was 0.48 by weight of cement.

May 19, 2016 · The foam present in ICFs is coated with flame retardants so it is not susceptible to fire. In several tests, concrete walls and ICF can stand exposure to intense heat and flames up to 2000 F for a maximum of four hours. In contrast, homes made from wood frame and other materials break down in less than an hour.

Concrete made from fly ash and other industrial waste products could lower the carbon emissions associated with large construction projects, according to scientists at Kaunas University of Technology (KTU) in Lithuania.
The above plastic wastes were mixed with cement concrete in various proportions (0.1% to 2%) and test specimens were cast (cubes and columns) to study the behavior of plastic mixed concrete in axial compression. S. Gowri, Senior Lecturer, and N. Rajkumar, Lecturer, Dept of Civil Engg, Erode Sengunthar Engineering College, Thudupathi, Erode
and durability of the concrete mix specimens obtained from the addition of these materials is compared with control concrete mix. The test results showed that a significant improvement in compressive strength was achieved in the E-waste concrete compared to conventional concrete and can be used effectively in concrete. 2.
Jul 29, 2016 · Inspired by the work of Peter Lewis, a New Zealand-based engineer whose research laid the foundation for the use of waste plastic to create building materials, Gomory created RePlast, a material comprising plastic sourced from the oceans and machine-compressed into the dimensions of a typical concrete masonry unit.

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (for its visual resemblance to ...

The construction industry consumes enormous quantities of concrete, which subsequently produces large amount of material waste during production and demolishing. As a result, the colossal quantity of concrete rubble is disposed in landfills. This paper, therefore, evaluated the feasibility of reusing waste concrete as recycled aggregate (RA) to produce concrete. The …
Recycling Waste Concrete. Every year millions of tonnes of concrete rubble is generated in this world due to various reasons such as: (a) Distructions of cities during the wars and earthquakes. (b) Rejected precast concrete elements. (c) Testing of concrete cubes. (d) Concrete pavements reaching the end of their useful life.
The aim is not only to make the cements and concrete less expensive, but to provide a blend of tailored properties of waste materials and portland cements suitable for specified purpose. This requires a better understanding of chemistry, and materials science.

Ceramic tiles were sieved into fine and coarse aggregates in line with standards. Other materials used were gravel, river sand, cement and potable water. Workability of the fresh concrete was checked through slump test, and concrete cubes of 150 mm dimensions and cylinders of 100 mm ? 200 mm were cast in the laboratory.
Concrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate.
