strength and durability studies on concrete made artificial sand

Durability of concrete may be defined as the ability of concrete to resist weathering action, chemical attack, and abrasion while maintaining its desired engineering properties. Different concretes require different degrees of durability depending on the

By replacing 10 per cent of that sand with finely ground plastic particles, the Bath team estimates that over 800 million tonnes of sand could be saved. Published in the journal Construction and Building Materials, the research explored the impact of five finely graded plastics on the structural strength of concrete tubes and cylinders.

The strength of concrete is measure in terms of pounds per square inch (or PSI). PSI is a measure of compressive strength, or the ability of the material to carry loads and handle compression. 1.) 2500-3000 PSI. Most concrete has a PSI rating of 2500 to 3000. This type of concrete can be used for sidewalks and residential driveways.

RCA concrete has unit weight in the range of 2240-2320 kg/m3.It has higher water demand and gave lower compressive strength than control concrete made from natural aggregate at equal water to cement ratio RCA concrete has similar flexural strength but lower elastic modulus than control.

Bricks made from sand and waste plastic bottle (specimen PB) recorded highest compressive strength of 10.6 MPa. However, normal clay bricks (specimen NB) presented a low compressive strength of 1.77 MPa. It may be noted that bricks made from sand and waste plastics could be used suitably in construction works. This practice will

Higher concrete strength compared to river sand used for concreting. Lesser concrete compared to M Sand. Silt Content. Zero silt. Minimum permissible silt content is 3%. Anything more than 3% is harmful to the concrete durability. We can expect 5 - 20% slit content in medium quality river sand. Over Sized Materials.

Around A.D. 79, Roman author Pliny the Elder wrote in his Naturalis Historia that concrete structures in harbors, exposed to the constant assault of the saltwater waves, become "a single stone mass, impregnable to the waves and every day stronger." He wasn't exaggerating. While modern marine concrete structures crumble within decades, 2,000-year-old Roman piers and

The study conducted by Columbia University on mortars and concretes manufactured by replacing raw sand with dredged marine material of a very fine fraction (10 μm) revealed that the strength reached by those made with part of dredged material was lower than that of the control mixture, and the mixtures were less workable. However, the increase in strength over time was higher than in

The necessity of Fiber Reinforced Concrete. It increases the tensile strength of the concrete. It reduces the air voids and water voids the inherent porosity of gel. It increases the durability of the concrete. Fibers such as graphite and glass have excellent resistance to
