7 Causes of Cracks in Reinforced Concrete Slabs: Numerous variables, such as poor concrete quality, insufficient structural design, insufficient steel bar spacing, wide slab span, and inadequate aggregates, contribute to the formation of cracks and fissures in RCC slabs. While concerns relating to faulty structural design may be prevented at the design stage of the …
Failed slump test: Should engineers allow the contractor to continue concreting if the on-site slump test fails? This is a pretty traditional issue that many graduate engineers pose. Here, we are going to spot some light on the answer. When an on-site slump test fails, engineers must make an appropriate conclusion. The choice may be …
Carbonation of Concrete Carbonation Test of Concrete: Carbonation of concrete occurs when carbon dioxide in the air reacts with calcium hydroxide and hydrated calcium silicate in the concrete, resulting in the formation of mostly carbonates (CaCO3). Carbonates are formed during these chemical reactions, resulting in the permanent retention of this CO2. Carbonation happens when CO2 …
Rapid Chloride Permeability Test (RCPT) Rapid Chloride Permeability Test: This test method is used to provide an indication on the penetrability of concrete. It is used for evaluation the resistance of a concrete sample to the penetration of chloride ions. Today, several concrete buildings are constructed to requirements of low-permeability concrete. RCPT is widely accepted …
Supervising Stone and Brick Work What is Masonry Work? Supervising Stone and Brick Work: Masonry work refers to the building of structures using small blocks which include bricks, stones, concrete bricks etc. This construction method requires considerable physical and mental requirements. Increasing the tasks requirements causes higher likelihood for errors, reworking, safety concerns and productivity …
Concrete Frame Structures: Concrete frames are probably the most the used structural system worldwide. This kind of building is made of frames of concrete. Horizontal members are called beams, and vertical elements are columns. Between the beam, there is a flat plane of concrete called slab, where humans walk on. Load is transferred from the …
Setting Time of Cement: Hydraulic cementitious materials have a unique feature, which is they are moldable and castable materials in their early age once mixed, and then they transform into a solid/hard material with much useful engineering characteristics. Hydration is the process that causes this structural transformation from plastic to hard material. Hydration refers to …
Benefits of Using Recycled Aggregate in Concrete Benefits of Using Recycled Aggregate: With more companies and customers becoming more environmentally conscious, pressure has risen on enterprises to utilize more sustainable materials – aggregates are a good example of this. Recycled aggregates have become a popular alternative to conventional aggregates. For example, in the UK, around …

Using Glass in Building: Since 500 BC, humans has found glass to be a fascinating substance. Glass, formerly believed to hold magical abilities. It is among the most flexible and oldest construction materials available. From its modest origins as a window pane in Pompeii’s luxury homes to complex structural elements in modern era structures, the …
