Mass concrete or massive pours is defined as any volume of concrete with dimensions bigger enough to require measures to deal with the generation of heat from the hydration of cement & adjustments within the attendant quantity to reduce cracks. Concrete of large or massive structures has always posed a…
What is Hot Weather Concreting? Preventive Measures in Hot Weather Concreting
What is Hot Weather Concreting? Hot weather concreting is described as one or a combination of the conditions such as high ambient temperature, high concrete temperature, low relative humidity, and high wind speed that tend to impair the quality of freshly mixed or hardened concrete by accelerating the rate of…
Different Types of Cracks in Concrete
Cracks might be big or small, structural or non-structural. All of them can be a nuisance by way of either marring the appearance or function as a passage for atmospheric polluting gases or moisture to enter the body of concrete and cause distress. Cracks in the concrete structure do not…
Transparent Concrete – Its History, Properties, Applications, Advantages, and Disadvantages
What is Transparent Concrete? Transparent concrete is hardened concrete that allows light to pass through it. It is also known as light-transmitting concrete or translucent concrete. Commonly, transparent concrete is similar to ordinary concrete because the strength of both concrete is similar. But the major advantage is the transparent concrete…
What is Rebar Coupler? Its Types, Advantages, and Disadvantages
Rebar coupler or mechanical splices are utilized in reinforced concrete structures to replace normal rebar lap joints. The rebar coupler is also suitable for use in reinforced concrete columns & walls. Rebar coupler consists of a piece of rebar equipped with a thread & coupler sleeve at the right end…
Why Does Concrete Needs Repair? Repair Components and Right Materials
Concrete repair is the procedure of fixing a hardened concrete surface that over time has lost the ability to hold the binding concrete materials together because of environmental exposure or damage. Concrete repair is appropriate for cracks, physical impacts, surface scaling, or chipped-out surfaces. Why Does Concrete Needs Repairs? There…
What is Engineering Grout? Its Types, Properties, Applications
Engineering grout is a material that has properties on non-shrink, free flow, high early strength for bolt pocket, and base plate of machines to ensure firm and vibration-free equipment. Engineering grout is composite material generally consisting of water, cement, and sand. Engineering grout is normally utilized for filling voids under…
Different Field Tests of Aggregates
There are simple field tests of aggregates that are required to be carried out in the field to enable the site supervisor to determine the quality and the proportions required to be taken in the concrete mixes. Before the tests are performed, it is very important to collect a proper…
What are the Properties of Aggregates for Concrete?
In concrete, fine aggregates and coarse aggregates make up about 75% of the total concrete materials. It is, therefore, significantly important to acquire the right type and quality of aggregates at the site. The aggregates from the main matrix of the concrete/mortar. The aggregate particles are glued together by the…
What is Structural Appraisal? Principles and Guidelines for Structural Appraisal
A structural appraisal is concerned with establishing the strength of an existing structure and reporting on its safety & its fitness for a given purpose. As the structure being appraised exists, many uncertainties that existed and assumptions made during its original design can now be incorporated into the appraisal review…
