Recyclable Waste Material as Substitute Aggregate in Concrete Cannon M. Lynch Construction Management B.S. California Polytechnic State University San Luis Obispo, California Trash pollution is a serious problem that the world is facing and while there are current efforts to
Basically it consists of aggregates which are bonded together by cement and water. The major part of concrete besides the cement is the aggregate. Aggregate include sand and crushed stone / Gravel. Use of these conventional materials in concrete is likely to deplete the resources unless there is a suitable substitute.
Concrete is made of matrix which is cement paste and aggregate( Coarse and fine),the strength of concrete comes from the strenght of matrix and aggregate and in addtion to the bond between ...
fine pumice aggregate ratio was 1:3 for PA mortar. Pumice aggregate was substituted in weight ratio of of each sand size fraction required for CEN standard sand with the requirements of TS EN 196-1. The grain-size distribution of CEN standard sand and pumice aggregate (PA) was given in Table 2.
The new application of copper slag as a partial substitute for sand also triggered the change of the Singapore's Aggregates Standards which allows both natural and non-natural aggregates, including recycled aggregates, in concrete, thereby, opening the door to the use of more recycled/waste materials in concrete production.
The physical and chemical properties of copper slag were investigated. Copper slag, in amounts of 20, 40, 60, 80, and 100 percent, was substituted for fine aggregate in cement mortar and concrete. The fineness modulus of the combination of copper slag and fine aggregate was roughly 2.6, the optimum fineness modulus for concrete mix design.
Aggregates - Portland Cement Association. 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.
River Sand Substitutes. Sand Researchers world over are in continuous search for the alternatives to sand. Fine aggregate is one of the important constituents of concrete and mortar in construction industry. River sand is becoming a scarce material. Sand mining from our rivers has become objectionably excessive.
The availability of sand at low cost as a fine aggregate in concrete is not suitable and that is the reason to search for an alternative material. Quarry dust satisfies the reason behind the alternative material as a substitute for sand at very low cost.
Concrete with glass aggregate is a material mixture that has a lot of potential but also a lot keeping it from reaching this potential. Any type of glass when broken down to about #8 to #4 sieve. With compression strengths comparable to that of normal weight concrete and when glass powder has the same glueing effect as cement, Glascrete is the ...
The new application of WCS as a partial substitute for sand also triggered the change of the Singapore’s Aggregates standards which allows both natural and non-natural aggregates including recycled aggregates in concrete, thereby opening the door to the more use of recycled/waste materials in concrete production.
All of the above materials become fireproof when mixed with the GigaCreteâ„¢ binder and can be made very lightweight with strengths close to, and even exceeding, traditional concrete.

An aggregate is a collection of items that are gathered together to form a total quantity Aggregate (composite), in materials science, a component of a composite material used to resist compressive stress Construction aggregate, materials used in construction, including sand, gravel, crushed stone, slag, or recycled crushed concrete .
Acrete, a new substitute for concrete, is lighter, stronger and less expensive than concrete, and uses three times as much waste and converts it into useful building material. Acrete is a lighter, stronger and less expensive substitute for concrete
II. DIFFERENT ALTERNATIVES MATERIALS TO RIVER SAND The world is resting over a landfill of waste hazardous materials which may substitutes for natural sand. Irrespective of position, location, scale, type of any structure, concrete is the base for the construction activity.

Crushed Cement Concrete Substitution for Construction Aggregates—A Materials Flow Analysis. By Thomas Kelly. ABSTRACT. An analysis of the substitution of crushed cement con-crete for natural construction aggregates is performed by using a materials flow diagram that tracks all material flows into and out of the cement concrete portion of the ...
Fine aggregate used was clear sand passing through 4.75mm sieve with a specific gravity of 2.64. The grading zone of aggregate was zone III. Coarse Aggregate Coarse aggregate used was angular crushed aggregate with a specific gravity of 2.8. Concrete Mix Design Design concrete mix of 1:1.05:1.71is adopted to attain 80N/mm2. The water cement ...
