More performance tests are also used to test aggregates in concrete. A typical consensus specification for fine and coarse aggregate for concrete is ASTM C 33. Synthetic aggregates may be either byproducts of an industrial process, in the case of blast-furnace slag, or products of processes developed to manufacture aggregates with special
Coarse aggregates are divided into classes based on quality requirements as noted in the Classification of Aggregates table. Class AP is the highest class and is assigned to aggregates which m eet the requirements for all INDOT uses. Some INDOT contracts specify type AP aggregates for use in specific applications of portland cement concrete.

Specifications for construction aggregates have been developed for a variety of construction applications. The most important construction materials specifications for aggregates are for roadway and pavement construction (including hot-mix asphalt, granular base and granular sub-base), and for concrete materials used in buildings, civil engineering structures and infrastructure construction.
Description. This work shall consist of the final surface preparation and construction of a latex modified concrete (LMC) or very early strength latex modified concrete (VESLMC) overlay, and shall include all labor, materials, and equipment necessary to perform the work in conformity with the plans and specifications.

1.1 This specification defines the requirements for grading and quality of fine and coarse aggregate (other than lightweight or heavyweight aggregate) for use in concrete. 2 1.2 This specification is for use by a contractor, concrete supplier, or other purchaser as part of the purchase document describing the material to be furnished.
Apr 19, 2020· The aggregates are broadly classified into two types based on the size, namely- fine aggregate and coarse aggregate. In this article, we discuss the properties of the standard aggregates used in the production of concrete as per the American Standards (ASTM- C33/C33M).
This standard is issued under the fixed designation C 33; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of
ASTM C33/C33M, 2018 Edition, March 15, 2018 - Standard Specification for Concrete Aggregates This specification defines the requirements for grading and quality of fine and coarse aggregate (other than lightweight or heavyweight aggregate) for use in concrete. 2 This specification is for use by a contractor, concrete supplier, or other purchaser as part of the purchase document describing the ...
The aggregate should meet the staining requirements of ASTM C330, Standard Specification for Lightweight Aggregates for Structural Concrete (AASHTO M 195) when tested according to ASTM C641, Standard Test Method for Iron Staining Materials in Lightweight Concrete Aggregates
Designation: C33/C33M − 13 Standard Specification for Concrete Aggregates 1
This paper reviews existing specifications, specifically for the application of crushed concrete or recycled concrete aggregate (RCA) as pavement material for unbound subbases and basecourses.
Aug 11, 2018· Aggregates are one of the most important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 60 to 80 % of total volume of concrete. So, we can say that one should know definitely about the aggregates in depth to study more about concrete. Aggregate may be natural, […]
This specification defines the requirements for grading and quality of fine and coarse aggregate for use in concrete. Fine aggregate shall consist of natural sand, manufactured sand, or a combination thereof. Fine aggregate shall be free of injurious amounts of organic impurities.

The important characteristics of aggregates for concrete are listed in Table 5-2 and most are discussed in the following section: Grading. Grading is the particle-size distribution of an aggregate as determined by a sieve analysis (ASTM C 136 or AASHTO. 80.
ASTM C33-02 Standard Specification for Concrete Aggregates. 1. Scope1.1 This specification defines the requirements for grading and quality of fine and coarse aggregate (other than lightweight or heavyweight aggregate) for use in concrete.1.2 This specification is for use by a contractor, concrete supplier, or other purchaser as part of the purchase document describing the material to be ...
Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the ...

Important Aggregate Dos and Don'ts. DO use aggregate that's in compliance with ASTM C 33, "Standard Specifications for Concrete Aggregates." Aggregates must be sound, clean, hard, durable, and free of excessive fines or contaminates that can affect cement hydration or disrupt the paste-aggregate bond.
