How long before you can paint new concrete? Allowing the new concrete to cure for at least 30 days can reduce the alkalinity and moisture content to levels low enough for the concrete to take paint. But it can take as long as 60 days before new concrete has cured enough for painting, depending on climate and weather, reports Jon-Don.

Can you pour concrete in freezing temperatures?

Use concrete curing blankets to prevent freezing and keep the concrete at an optimal curing temperature.
What is split face concrete block?
Splitface Concrete Blocks have a deep textured relief which gives depth to the unit while also exposing the inner aggregates. This lends itself to customization through the use of different colored aggregates.
What does slump in concrete measure?
A concrete slump test measures the consistency of a concrete batch to see how easily the concrete will flow. The test not only observes consistency between batches, but it also identifies defects in a mix, giving the operator a chance to amend the mix before it is poured on site.

Why is a flexure test performed concrete?
The most common purpose of a flexure test is to measure flexural strength and flexural modulus. Flexural strength is defined as the maximum stress at the outermost fiber on either the compression or tension side of the specimen. Flexural modulus is calculated from the slope of the stress vs. strain deflection curve.
