Sometimes two rights make a wrong. Steel is efficient and resourceful, and builders can assemble it fast and convenientlyduringall seasons. Steel is flexible and flexes under extreme pressure or loads instead of crumbling or crushing. Steel requires minimal onsite labor since most components are pre-manufactured. Once the cement is mixed with small stones, sand, gravel, and water, concrete is made. The minimum strength requirements for this type of blocks are 4Mpa. It is one of the oldest types of mortar, used widely in ancient Construction. Disadvantages of Foam Concrete With a decrease in the density of foam concrete, its compressive and flexural strength decrease. They are being manufactured by a lean mix of concrete having the size of aggregate less than 12mm. It is very evenly coloured, easy to shape and the texture improves with time. Thousands of condemned buildings are demolished each year. For example, concrete allows lower construction costs in exchange for a longer construction time, while steel is preferred when fast construction is the priority. One of the major disadvantages of reinforced concrete is the lack of tensile strength. In shoring and strutting work in foundations, steel sheets are widely used to stabilise the lateral thrust exerted by the surrounding soil. Green concrete is an environment centered thinking concept as far as concrete is concerned. It is Generally green, Yellow or brown in colour. This type of glass is Generally Manufactured from a Mixture of Potassium Silicate and Calcium Silicate. Plain cement concrete is obtained by mixing cement, water, sand, and gravel in definite proportions. Green concrete not only helps in recycling of industrial waste, but also solve the disposal problem. Numerous industrial wastes can be recycled to normal aggregates and cement substitutes. Reinforcedconcrete has an excellent thermal mass and is fire resistant. Disadvantages. No environmental pollution and sustainable development. Architects can create free-form combinations for facades and segmented curves because steel can bend to a certain radius. Improve damping resistance of the building. This type of concrete uses steel rods, wire mesh, and cables to increase its overall strength. Nowadays, there are around 10000 types of plastic available on the market, which owes to the tremendous increase in the production of plastic due to technological upgradation. it is costly as it consumes much effort and very high temperature to Manufacture. ; The application of refractory concrete also includes in the construction of fire training areas which consists of wide flat surface areas with fire .
