Exposed-aggregate concrete pavement. Both gravel and crushed stone produce quality concrete. Gravel will have a lower water demand compared to crushed stone. Gravel is preferred for exposed-aggregate concrete in walkways and decorative applications. Crushed stone will usually exhibit a higher paste-aggregate bond.Aggregates - The Portland Cement Association,Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed.Aggregates for Concrete - GreenSpec,Recycled concrete is created by breaking, removing, and crushing existing concrete to a preferred size. It is commonly used as a base layer for other construction materials. Recycled concrete can be used as aggregate in new

What is aggregate? In concrete, aggregate is the granular substance that holds the mixture together in its solid form. Aggregates vary in size and shape, and they can be as finely ground as sand or as coarse as gravel. When mixed with water and cement, these compounds form concrete.HOW TO DECIDE MAXIMUM SIZE OF COARSE,For the same strength or workability, concrete with large size aggregate will require lesser quantity of cement than concrete with a smaller size aggregate.HOW TO CLASSIFY AGGREGATES ACCORDING,According to size the aggregates are classified as: Fine Aggregate Coarse Aggregate All in Aggregate Fine Aggregate It is the aggregate most of which,

Grading of coarse aggregate: The coarse aggregate grading limits are given in IS 383 – 1970 – table 2, Clause 4.1 and 4.2 for single size aggregate as well as graded aggregate. The grading of coarse aggregate is important to get cohesive & dense concrete. The voids left by larger coarse aggregate particles are filled by smaller coarse aggregateHOW TO CLASSIFY AGGREGATES ACCORDING,For example 20 mm single size aggregate mean an aggregate most of which passes 20 mm IS sieve and its major portion is retained on 10 mm IS sieve. All in Aggregate. It is the aggregate composed of both fine aggregate and coarse aggregate. According to size All-in-aggregate is described as all-in-aggregates of its nominal size, i.e. 40mm, 20mm etc.coarse aggregate - Deutsch-Übersetzung ,Viele übersetzte Beispielsätze mit "coarse aggregate" – Deutsch-Englisch Wörterbuch und Suchmaschine für Millionen von Deutsch-Übersetzungen.
Generally the size of coarse aggregate used is 10-12.5 mm. If we use the proportional mix of different sizes small to large (>4.5 mm to 20/25 mm), this make the concrete structure compact by align themselves in voids depending upon their size and compact mass will be formed with increased strength.ACI Education Bulletin E1-99 AGGREGATES FOR CONCRETE,acceptance of an aggregate for use in concrete on a particular job should be based upon specific information obtained from tests used to measure the aggregate quality, or upon its service record, or both. A typical consensus specification for concrete aggregate, both fine and coarse aggregate, is ASTM C 33.ASTM C33 / C33M - 13 Standard Specification,C33/C33M - 13 Standard Specification for Concrete Aggregates , aggregates, coarse aggregate, concrete aggregates, fine aggregate,
Aggregate plays a vital role in providing strength to concrete. without aggregate, it remains mortar only. Bigger the size of aggregate, more strength it will provide. But aggregate size must be 5 mm bigger than the dia. of largest bar used in any element. Mostly used aggregate size is 20 mm. maximum.aggregates In Concrete - Uw Courses Web Server,( 6 in.) coarse aggregate. Aggregates in Concrete. Professor Kamran M.

Some researchers have proposed to use waste glass as aggregate, filler, or supplementary cementitious material in concrete and asphalt not only to reduce the cost of concrete but also to provide a solution for waste disposal and the related environmental problems   .IS 383: Coarse and Fine Aggregate for Concrete,,In order to promote public education and public safety, equal justice for all, a better informed citizenry, the rule of law, world trade and world peace,The role of aggregate in concrete countertop,Concrete made with just fine aggregate (or sand) is known as mortar concrete. Like the mortar used for brick and concrete block construction, which is simply made with mortar cement and sand, mortar concrete has no coarse aggregate in it, so a ground finish will have a fine-grained appearance.
