This study investigates the effects of sieved wastes generated from the brewing industry on lightweight aggregates manufactured with clay. Sludge from a wastewater treatment plant, bagasse and diatomaceous earth were used to obtain the samples. These wastes are usually dumped in landfills, but the current increase in restrictions on dumping and interest in improving the environment make our pro...

The study of water absorption soft rock is great significance to the prevention engineering disasters. However, research on prediction method considering influence composition, porosity, and solute insufficient. Aiming solve above problem, tests are carried out by synthesizing rocks solutions. Then, model established through quantitative analysis data compared with characteristics natural verif...

Four different composite mixtures with varying amounts of expanded vermiculite were exposed to high temperatures of 300, 600, 900 and 1100uC for 6 h. Physical and mechanical properties including unit weight, porosity, water absorption, residual compressive strength, residual splitting tensile strength and also ultrasonic pulse velocity were determined after air cooling. Microstructures were inv...

We have studied the compaction of vapor-deposited amorphous solid water by energetic ions at 40 K. The porosity was characterized by ultraviolet-visible spectroscopy, infrared spectroscopy, and methane adsorption/desorption. These three techniques provide different and complementary views of the structural changes in ice resulting from irradiation. We find that the decrease in internal surface ...

The objective of the present manuscript is to describe impact polypropylene fibers on behavior heated concrete subjected heating and cooling cycles at temperatures 200, 450 600 °C respectively for six hours, through a series experimental tests mass loss, water absorption, porosity, compressive tensile strength. For this purpose, mixes were prepared with water/cement ratio incorporation rate var...
