Early-age cracking is observed during the first seven days after concrete pouring. However, such cracks may also take more than a week to be visible in reinforced concrete slabs. Therefore, cracks appearing within 60 days after the concrete placement are ...

How to Minimize Rate of Evaporation from Concrete Surface?
A high rate of evaporation from the concrete surface leads to quality, durability, and potential strength-related issues. Plastic shrinkage cracks are highly likely to occur if the evaporation rate is higher than 1 Kg/m2/hour. Therefore, appropriate actions to slow down ...
Metal Ceilings: Types and Features
Metal ceilings are architectural ceiling elements made from finished metal plates with designs pressed into them. Metal ceilings can be made from aluminum, steel, or galvanized iron. Metal ceilings add strength to the structure and are highly durable compared to ...
What are the Risks of Pouring Concrete at a Wrong Temperature?
Placing concrete at the correct temperature is critical for its durability and ultimate strength. This is because temperatures above the normal concrete curing range (32 °C) will not only reduce the workability of concrete but also cause a significant reduction ...
What is Oxicrete in Construction?
Oxicrete is an acid system applied to cement surfaces like dam structures, polymer-modified screeds, and mortars to oxidize them and provide a stone-like or rusty iron appearance. The thickness of the coating ranges from 3-6 mm and provides a smooth ...
Carbon Concrete: Production and Advantages
Carbon concrete is a sustainable construction material produced from concrete and carbon fibers or bars. The carbon is incorporated into the concrete through mesh-like textile mats placed between its layers or as randomly or uniformly dispersed fibers throughout the concrete. ...
Timbercrete: Components, Advantages, and Applications
Timbercrete is an environmentally friendly construction material, produced from a mixture of sawdust and concrete. It reuses waste products and replaces some energy-intensive components of conventional concrete. So far, timbercrete has been used to produce bricks, blocks, panels, and pavers, ...
Construction Tolerances for Cast-in-Place Concrete Members in a Building
Construction tolerances are allowed variations in a designated dimension of cast-in-place reinforced concrete elements. They are necessary means of controlling vertical element plumb, size, length, and location of various cast-in-place concrete elements in a building. This is because structures are ...
