Compressive Strength of Concrete: What Causes Low-Strength Breaks in Concrete Cylinders?
The compressive strength test results of concrete cylinders are the basis of acceptance of ready mix concrete for construction. Low-strength breaks of the concrete cylinder during compression testing indicate the low compressive strength of produced concrete. Concrete cylinders for the ...
NeoConcrete: Applications and Advantages
NeoConcrete is a construction material that creates a continuous coating of 0.4 cm thickness for walls, floors, and exteriors that resembles terrazzo or granite finish. It is produced from a mix of cement, decorative aggregate, and resin. The most common ...
How can Lignin Help Improve Concrete Construction?
Lignin is a wood waste, which after necessary processing, can be used in the field of building materials and construction as a water-reducing admixture, set retarder, grinding agent in cement production, cement replacement materials, etc. It makes concrete stronger by ...
How to Prevent Reinforcement Corrosion on Site?
Corrosion of steel bars is highly detrimental for reinforced concrete elements and might undermine their serviceability and even cause structural failure. However, various precautions can be taken to prevent corrosion of steel bars on construction sites. Concrete with high quality ...
How can Embodied Carbon be Used to Reduce Global Warming?
The use of carbon dioxide directly i.e. without chemical modification, or after chemical conversion processes for the production of building construction materials is a key strategy to mitigate climate change and use resources efficiently. Researchers have been relentlessly conducting investigations ...
Concrete Slump Variations at Site: How to Deal with it? Explained with Video
Adjusting the slump of concrete is a part of the concreting process, which the contractors should manage properly and cautiously. The concrete slump variation from one transit mixer to another is generally due to aggregate moisture content, concrete temperature, mixing ...
Failed Concrete Slump Test? Here is What you Should do
Engineers should make a proper decision when an on-site slump test fails. The decision could be an outright rejection of the complete batch of concrete or the suspension of the work due to the contractor’s failure to follow project requirements. ...
