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
What is Polyjacking? Polyjacking is a method of lifting and leveling concrete that uses high-density geotechnical foam to lift and stabilize the concrete surface. A similar process with the same goal is the mud-jacking process, which uses mud instead of foam to lift the concrete surface to the desired level. This article describes the main … Read more

It is very important to check the quality of sand on construction site. Bad quality of sand can impact the quality of concrete. Sand is one of the most important constituents of concrete. The main purpose of adding sand (fine aggregate) to concrete is to fill the gaps between coarse aggregates. Then fill the gaps … Read more
In this article, we will talk about how to consolidate concrete in congested reinforced concrete members. The problem of concrete consolidation is occur due to congested reinforcement. In the congested reinforcement, concrete vibrator can not work properly. Fresh concrete consolidation of contested concrete members should be performed using appropriate concrete pouring and compaction methods. Otherwise, … Read more
Post-concreting defects of structures are defects that are visible after the formwork has been removed. We will discuss the repair of these defects after concrete placement, the materials, equipment and repair methods required. Key Important Things to be Remembered for Repair of Post Concreting Defects There are four important things that should be considered while … Read more
It is important to determine the effects of excess water in concrete. Too much water in the concrete mixture makes it easier to lay concrete, but it also reduces the quality of the overall concrete product. The adverse effects of having too much water in a concrete structure are very common, and this article outlines … Read more
The cylinder test of concrete is used to determine the compressive strength of concrete. The compressive strength of concrete is one of the most basic things considered when designing structures. The Cylinder Test of Concrete is the alternative to the concrete cube test. In some countries, a cube test is performed and in others, a … Read more
Top down method is the reverse construction method of the bottom-up technique. In this method, a permanent structure is built from top to bottom of the basement along with deep excavations. In this method, a basement is built as earthworks progress. Concrete slabs in the basement serve as side braces for the surrounding wall system. … Read more
