The Dusty Dangers of Concrete Cutting & Grinding

Concrete cutting and concrete grinding are very dusty jobs in the construction industry, both posing a serious health risk to masons. Masonry blocks, bricks, and concrete slabs contain concentrated amounts of crystalline silica. When these materials are dry-cut they release silica containing dust into the workers' breathing zone. Regular exposure to this hazardous dust canUse of Quarry Dust to Replace Sand in Concrete – An clear picture that quarry dust can be utilized in concrete mixtures as a good substitute for natural river sand giving higher strength at 50% replacement. Index Terms- Concrete, quarry dust, river sand, compressive strength. I. INTRODUCTION oncrete is the most widely used composite material today.

Study on Compressive Strength of Quarry Dust as Fine

The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete is not suitable and STRENGTH AND DURABILITY STUDIES ON CONCRETE USING Quarry Dust. iv. Concrete using 25% natural sand and 75% Quarry Dust. Key words: Durability, Quarry dust, Material test. 1. INTRODUCTION In the context of increased awareness regarding the ill effects of the over exploitation of natural resources, eco –friendly technologies are to be developed for effective
