Existing studies have shown that partially replacing fine aggregates with mechanically recycled FRP powder exerts no negative impact on the durability of Portland cement concrete and mortar. Tittarelli and Moriconi [ 18 ] studied the alkalisilicon reactivity of powdered GFRP, and the results did not reveal any potentially harmful reactions.

from floor to floor) If the aggregate is deep it will not be worth grinding that deep. Running the grinder at a low RPM may increase grinding speed in the course steps (14 and 30 Grit) by allowing the diamonds to penetrate the floor without overheating. This is most effective on soft concrete or concrete less than a year old. Experiment with speed

Cement is seldom used on its own, but rather to bind sand and gravel ( aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's mostconsumed resource.

Factors Affecting Strength of FineGrained Concrete. As finegrained concrete is a concrete rich with sand and filler particles, the primary factor that governs its strength is the quality of fine aggregates. The quality of fine aggregates influences the basic properties of finegrained concrete to a higher extent than for conventional concrete.
