What is aggregate in concrete mix?

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. Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter.

How much aggregate do I need for 1m3 of concrete?

4 Answers from MyBuilder Groundworkers. For 1m3 of footing you need 2 tonne of aggregate and 10 – 12 bags cement, so for 1.6m3 you need 3.2 tonnes and about 18 bags of cement. Personally I would consider getting a concrete company to deliver 1.6m3.

Do I need aggregate in cement?

Aggregates make up 60-80% of the volume of concrete and 70-85% of the mass of concrete. Aggregate is also very important for strength, thermal and elastic properties of concrete, dimensional stability and volume stability. Including aggregate in the mix can control the shrinkage level and prevent cracking.

Which shape of aggregate is good for concrete?

The shape and texture of aggregate affects the properties of fresh concrete more than hardened concrete. Concrete is more workable when smooth and rounded aggregate is used instead of rough angular or elongated aggregate.

Which shape of aggregate gives maximum strength?

Aggregate particles that are cubicle or spherical in shape and correct mineral composition are ideal for maximizing concrete strength. The use of flat and elongated aggregate particles should be avoided or at least limited to a minimum of 15 percent.

What is aggregate shape?

The different shapes of aggregates are: Rounded – Natural aggregates smoothed by weathering, erosion and attrition. Rocks, stone, sand and gravel found in riverbeds are your most common rounded aggregates. Rounded aggregates are the main factor behind workability.

What is flaky aggregate?

Flaky aggregate is defined as an aggregate particle with a least dimension (thickness) less than 0.6 of the mean of the smallest sieve size through which the particle passes and the largest sieve size on which the particle is retained.

What is effect of flaky and elongated aggregates?

The results reveal that the effect of elongated aggregates is more than flaky aggregates, on the characteristic compressive strength of concrete. Concrete with 1:1 ratio of flaky to elongated aggregates possesses minimum weight.

What is the main function of set retarders?

9. What is the main function of set retarders? Explanation: Used to counteract hot weather conditions that cause increased rate of hardening. This makes placing and finishing difficult.

What is the use of superplasticizer?

Superplasticizers (SP’s), also known as high range water reducers, are additives used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.

What does admixture mean?

An admixture is defined as “a material other than water, aggregates, cementitious materials, and fiber reinforcement, used as an ingredient of a cementitious mixture to modify its freshly mixed, setting, or hardened properties and that is added to the batch before or during its mixing” (ACI Committee 212, 2010).

How many types of chemical admixtures are there?

five distinct

What is a retarding admixture?

Retarding admixtures are used to slow the rate of setting of concrete. By slowing the initial setting time, the concrete mixture can stay in its fresh mix state longer before it gets to its hardened form. Use of retarders is beneficial for: Complex concrete placement or grouting.

What is concrete workability?

Concrete workability basically refers to how easily freshly mixed concrete can be placed, consolidated and finished with minimal loss of homogeneity. Generally the workability of concrete is determined by how fluid the mix is (i.e. the cement to water ratio).

What are mineral admixtures?

Mineral admixtures refer to the finely divided materials which are added to obtain specific engineering properties of cement mortar and concrete. The mineral admixtures are generally used as partial replacement of portland cement, an expensive and energy intensive material.

How are mineral admixtures classified?

It has been concluded that mineral admixtures may be categorized into two groups: chemically active mineral admixtures and microfiller mineral admixtures. Chemically active mineral admixtures decrease workability and setting time of concrete but increase the heat of hydration and reactivity.

and other highly reactive mineral admixture like silica fume, metakaolin, etc. Fly ash and silica fume are the most commonly used two mineral admixtures. When OPC is replaced with fly ash the rate of strength gain of concrete is slower at early age./span>

What is meant by pozzolanic material?

A pozzolan is a siliceous or siliceous and aluminous material that in itself possesses little or no cementitious value but will, in finely divided form and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form compounds having cementitious properties.

Natural pozzolana is composed mainly of a fine, chocolate-red volcanic earth. An artificial pozzolana has been developed that combines a fly ash and water-quenched boiler slag. …made with volcanic-ash cement (pozzolana) permitted a great expansion of architectural methods, particularly…

Why is pozzolana added to cement?

As the definition implies, a pozzolan combines with calcium hydroxide in the concrete to form calcium silicate hydrate, similar to that produced by hydration of portland cement. Use of pozzolans may increase or decrease water demand depending on the particle shape, surface texture, and fineness. …

Why fly ash is added in cement?

Fly ash use in concrete improves the workability of plastic concrete, and the strength and durability of hardened concrete. Fly ash use is also cost effective. When fly ash is added to concrete, the amount of portland cement may be reduced. Benefits to Fresh Concrete.
