What are Rebar Couplers? Rebar couplers are used to joined steel bars together. Normally ends of steel bars are joined. These types of couplers are used in reinforced concrete structures to modify the reinforcement wrapping and welding system. Coupling is used when longer rods are needed or when additional rods are attached to the ends … Read more
Introduction of Pumped Concrete Pumped concrete is concrete that is pumped and transported by using special types of pumps. Mixed concrete can be transported easily from one place to another. This method is used when large amounts of concrete work are required at heights that are not easily achievable by other means of transport. Large … Read more
In this article we will discuss about difference between nominal mix and design mix of concrete. In the nominal mix of concrete, mixing is done at the construction site while design mix is prepared in ready mix concrete plants. What are the Differences Between Nominal Mix and Design Mix? Nominal Mix Design Mix When concrete … Read more

Some other names of plum concrete are cyclopian concrete and rubble concrete. It is a mixture of wet concrete and plums. Plus are … Read more
Introduction There are many possible causes of concrete deterioration. Concrete is most often damaged by corrosion of rebar due to carbonation of hardened cement paste or by chloride attack in wet conditions. Chemical damage is caused by various chemical reactions, aggressive chemical species (chloride, sulfate, magnesium ions) present in groundwater and seawater, or the formation … Read more
Introduction of Girder A girder is a member of a structural design system. Both girders and beams have the same function. These two elements carry and distribute structural loads. Many people equate bars and grids, but they are not. Both share the same functionality, but there are some key differences that distinguish them. This article … Read more
Introduction In this article we will discuss about young’s modulus of elasticity. I would recommend to read my article on stress-strain curve. In the article on stress-strain curves, we learned about proportionality limits, where we talked about constants. This constant is known as the Young’s modulus. Young’s Modulus of Elasticity Above graph is obtained by … Read more
In today’s blog article we are going to discuss very interesting topic ” Energy Performance Certificate (EPC)”. Energy Performance Certificate (EPC) An energy performance certificate is a certificate that indicates the energy efficiency of a building based on a rating from A (very efficient) to G (inefficient). I have shown a typical EPC document as … Read more
Sewage pump is a pumping device which transfer sewage from one palace to another palace without harming the environment. Sewage pumps move sewage solids and liquids from one place to another. In residential areas, sewage consists of soft solids up to 2 inches in diameter. Wastewater is channeled from the sump to a septic tank … Read more
Parallel seismic pile test is performed to check the quality of pile foundation. It is a non-destructive surface method used to test the quality of pile foundations. It is used to calculate the length and integrity of pile foundations that are not accessible (too long, too thin, or buried under pile caps). If we compare … Read more
