As the concrete has more water available to be utilized in the cement hydration process, enabling the concrete to not shrink for a longer length of time, the boost in the w/c percentage would result in a drop in shrinkage strain. With an increase in fiber content, shrinkage strain values reduced consistently across all fiber samples.

Basalt is a type of volcanic rock that is formed from the solidification of molten lava. It is an igneous rock, meaning it is formed through the cooling and solidification of magma or lava. Basalt is one of the most common rock types on Earth, and it can be found in various locations around the world, both on land and under the ocean floor.

The low tensile capacity of concrete often results in brittle failure without any warning. One way to cope with this issue is to add fibers and essentially improve the tensile strength (TS) behavior of concrete and offset its undesirable brittle failure.
