What is Plain Cement Concrete? Many different types of concrete are used in construction, one of which is PCC or plain cement concrete. As the name implies, this concrete contains no steel or reinforcement, only plain concrete. PCC is a mixture of cement, sand, aggregate and water. It has a high compression strength but a … Read more
TMT Bars | TMT Reinforcement Steel Bars Steel has been in the construction industry for a long time for its terrific properties such as Tensile strength, thermal conductivity, yield strength, and ductility. The role of steel in any building determines its structural strength and stability. Hence choosing the correct steel with desired properties is of … Read more
Reinforcements in a Reinforced Concrete Beam In RCC beams, elements are designed to resist the loads that cause bending moment, shear forces and sometimes in some cases, it also causes torsion along their length. It’s a known fact that concrete is strong in compression and very weak in tension. The steel reinforcement present in the … Read more
Ordinary Portland & Portland Pozzolana Cement Portland Pozzolana Cement – PPC Cement: Unlike Ordinary Portland Cement, Portland Pozzolana cement (PPC) is manufactured by combination of pozzolanic materials. Pozzolana is an artificial or natural material which has silica in it in a reactive form. Along with pozzolanic materials in specific proportions, PPC also contains OPC clinker … Read more
Field Tests for Cement Quality tests on cement at the construction site are performed to know the quality of the cement supplied, within a short amount of time. It is not possible to have laboratory tests done in the short period of time, hence in such times the basic field Tests for Cement are done … Read more
Effects of Corrosion in Reinforcement Corrosion in Reinforcement is a serious issue, it can affect the integrity and life of the structure. Concrete has mainly two protection mechanisms to protect the steel from corrosion. The first one is that it forms a physical barrier to avoid the steel come in contact with the external environment. … Read more
Lime Columns Method Lime columns method is a variation of deep soil mixing, in which unslaked quicklime is used instead of cement or mixed with cement. The lime columns are suitable at best for stabilization of deep soft clay deposits. A pozzolanic reaction takes place between the lime and the clay minerals resulting in substantial … Read more
Engineered Cementitious Composite This article will enlighten a unique construction material i.e. the flexible concrete also known as bendable concrete. This material can bring the revolution because of its some special quality such as flexibility, self-healing, lighter weight, etc. In some countries such as Japan, Korea, U.S.A, etc the flexible concrete is used in many … Read more
