Strength and Deformability of Fiber Reinforced Cement

The research object of the paper is cement paste with the particulate reinforcement of basalt fiber. Regardless of fibers' length at the same fiber cement mix workability and cement consumption equality compressive solidity of the specimens is reduced with increasing fiber content. This is due to the necessity to increase the water-cement ratio to obtain a given workability.

Because of the presence of such oxide minerals, basalt can acquire strong magnetic signatures as it cools, and paleomagnetic studies have made extensive use of basalt. In tholeiitic basalt, pyroxene (augite and orthopyroxene or pigeonite) and calcium-rich plagioclase are common phenocryst minerals. Olivine may also be a phenocryst, and when present, may have rims of pigeonite.

Sand and Gravel in Concrete

Jan 30, 2014Sand and Gravel in Concrete. The strength of the concrete is inversely proportional to the water/cement ratio. In other words, the more water you use to mix the concrete, the weaker the concrete mix. The less water you use to mix the concrete, the stronger the concrete mix. A mix with little water and more concrete mix will be dryer and less workable but stronger.
