Table 1) are achievable. The rate of concrete hardening and strength gain depends on the temperature of the concrete. Low concrete temperatures decrease the rate of hydration and subsequently ...

This requirement coincides with the minimum concrete strength requirement found in Table R402.2 of 2,500 psi. As a minimum requirements standard, the IRC does not provision for increased strength ...

A study reveals machine learning algorithms can predict compressive strength in concrete with waste glass powder, enhancing ...

Engineers at RMIT University in Australia have converted low-grade clay into a high-performance cement supplement, opening a ...

Measuring the strength of concrete in highways and bridges has traditionally entailed “heavy equipment, extensive labor, and considerable uncertainty,” says Luna Lu, an associate dean and ...

The invention is sensors embedded into a fresh concrete pour that can measure the concrete’s strength levels in real time, conveying when highway pavement is strong enough for traffic. These sensors ...

American Association of State Highway and Transportation Officials’ Committee on Materials and Pavements approves Purdue-invented method as a national standard for estimating concrete strength WEST ...
