Aggregates For Concrete

AGGREGATES FOR CONCRETE E1-3 sieve and predominantly retained on the 75 m No. 200 sieve is called fine aggregate or sand and larger aggregate is called coarse aggregate. Coarse aggregate may be available in several different size groups such as 19 to 4.75 mm 34 in. to No. 4 or 37.5 to 19 mm 1-12 to 34 in..

Fine Aggregate Its 6 Properties Amp Role In Concrete

Apr 12 2020 In concrete or mortar the aggregate is a granular material it is called fine aggregate when the particles of granular material are so fine that they can pass through a 4.75mm sieve. To increase the volume of concrete it is used in the construction industry and is cost-saving material. It consists of crushed stone and sand and quality .

Importance Of Gravel And Sand For Concrete Hunker

Smaller gravel particles equals a fine grade of concrete. Use the fine aggregate for concrete slabs or other smooth surfaces. A coarse aggregate means using larger pieces of gravel. Coarse concrete is helpful for sturdier projects. Concrete with a coarse aggregate doesnt produce a smooth look or feel but is stronger than a finer grade.

Concrete Aggregates Function Properties

An aggregate is considered unsound when the volume changes in aggregate induced by weather e.g. alternate cycles of wetting and drying or freezing and thawing result in the deterioration of concrete. IS limit Fine Aggregate 10 weight loss of five cycles with Na2SO4 Fine Aggregate 15 weight loss of five cycles with MgSO4

Effect Of Fineness Of Sand On The Cost And Properties Of

Concrete Mix Design Using Copper Slag As Fine Aggregate

Nov 10 2014 1. INTRODUCTION River sand is being used as fine aggregate in concrete for centuries. However river sand is not a renewable natural resource. In some regions river sand has been excessively exploited which has endangered the stability of river banks and the safety of bridges and creates environmental problems.

Concrete Fine Aggregate Alternate For River Sand

COMPARING THE COMPRESSIVE STRENGTHS OF CONCRETE MADE WITH RIVER SAND AND QUARRY DUST AS FINE AGGREGATES. River sand has been the most popularly used fine aggregate in the production of concrete but due to the overuse of the material our environment is the worst hit also the price of river sand has soar in recent times Sukesh at el 2013.
