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 considered early-age cracks. The early-age cracks do not cause structural failure in concrete if the […]

Mitigating early-age cracks in concrete structures is critical for sufficient durability, avoiding possible strength reduction, and reducing maintenance costs. Not only do early-age cracks diminish the aesthetic appearance of a building, but also make occupants uncomfortable and affect the contractor’s reputation. Therefore, suitable measures should be implemented to reduce or eliminate early-age crack development. The […]

Controlled low-strength material (CLSM) is a self-consolidating cementing material used primarily as an alternative to compacted fill (ACI 229R). It is intended to result in a compressive strength of 1200 psi or less. CLSM mixture usually consists of water, portland cement, fly ash or similar products, fine aggregates, coarse aggregate, or both. The material is […]

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 evaporation are necessary if it exceeds 0.5 Kg/m2/hour. It is found that the evaporation rate […]

Evaporation is a critical factor that must be considered while concrete is poured in hot weather conditions. If the rate of evaporation is high, concrete surface can lose water quickly, leading to workability issues and plastic shrinkage cracks. Plastic shrinkage cracks make the concrete vulnerable to ingression of water and chlorides and provide an unpleasant […]

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 in its ultimate strength. Similarly, low ambient temperatures, below 5 °C, slow the hydration process […]
