Gap-graded aggregate consists of coarse aggregate particles that are similar in size but significantly different in size from the fine aggregate. A core slice of gap-graded concrete shows a field of fine aggregate interspersed with slightly isolated, large aggregate pieces embedded in the fine aggregate.

However, for 25% replacement, additional cement content of 81.6 kg per m 3 of concrete was required to save 271.9 kg of conventional coarse aggregate per m 3 of concrete and at the same time getting added advantage of disposing 115.4 kg of waste coconut shell.

(read more about recycled aggregates) • Recycled Concrete. 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 concrete, particularly the coarse portion.

Gravels constitute the majority of coarse aggregate used in creating concrete with crushed stone. Again, our aggregates and gravel are certified state approved materials. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Our concrete recycling center is also a viable source of aggregate.

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. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel.

C33 - 18 Standard Specification for Concrete Aggregates , aggregates, coarse aggregate, concrete aggregates, fine aggregate ,,

Project Description. Construction aggregate, or simply “aggregate“, is a broad category of coarse particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.

2) Plastic: High-density polyethylene can be added to concrete and sand as a feasible replacement for coarse aggregate. Research has shown that plastic bags that are tightly packed and then heated, shrink to a size that can easily be used in concrete.

Material Alternatives Overview . Currently there is no proper replacement for the traditional aggregates for concrete. As will be discussed in list of materials below, every addition changes the concrete’s properties. At the cost of axial capacity, some add improved thermal, sound, and ductile properties to the mix.

Gravel, also called graded stone, is another coarse aggregate suitable for concrete mixes. Sand is the finest aggregate. It comes in different gradations: sharp sand, builder’s sand, and kiln-dried silver sand, which vary from coarsest to finest, respectively. Finer sands are a good aggregate for mortars and grouts.

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.

Gravels constitute the majority of coarse aggregate used in creating concrete with crushed stone. Again, our aggregates and gravel are certified state approved materials.

Using larger coarse aggregate typically lowers the cost of a concrete mix by reducing cement requirements, the most costly ingredient. Less cement (within reasonable limits for durability) will mean less water if the water-cement (w/c) ratio is kept constant.
