Measuring Compressive Strength - National Precast Concrete

The compressive testing process. A concrete compressive strength test machine works by progressively applying force on a specimen. Because strength is defined as the maximum load carried divided by the average cross-section area, the most logical way to determine the strength of a specimen is to load it until it fails.

Effect of moisture content on compressive and split tensile

that the moisture content in concrete does have a significant effect on the compressive strength of concrete, but has a much lesser effect on the split tensile strength. As the specimen degrees of saturation increased, the compressive strength fell. However, at nearly saturated condition, an increase in compressive strength can be found.

Concrete Block Vs. Brick

2017/07/17 · Both concrete block and brick masonry are strong, fire-resistant, insect-proof building materials. They have a lot of thermal mass, which helps them retain heat and makes up for their relatively low insulation value. However, despite their similarities, block and brick have some major differences.
