Though Concrete is one of the most widely used construction materials, there are lot of disadvantages associated with it. Some of these disadvantages of concrete are modified by adding admixtures or modifying the concrete structure and ingredients. Still there are lot of limitations associated with concrete.Major limitations of concrete are listed below.
Disadvantages of Concrete. With a decrease in the density of concrete, its compressive and flexural strength decrease. concrete has a relatively high paste content and no coarse aggregate, it will shrink more than normal concrete. Since it has higher cement content than normal concrete. So it becomes costly.
Air Entrained Cement. Air Entrained Portland Cement is a special cement that contains billions of microscopic air bubbles per cubic foot.These air bubbles provides the space for expansion of minute droplets of water in the concrete due to freezing and thawing.The air bubbles increase the workability of the concrete and lower the water cement ratio.However because of air entrained the …

CLC Blocks Manufacturing Process. ed concrete generally consists of a slurry of cement or fly ash, sand, and water. But some suppliers recommend pure cement and water with the ing agent for very lightweight mixes and sand is ignored. This slurry is then further mixed with a synthetic aerated in a concrete mixing plant.
We first discuss cement production and special nomenclature used by cement industrialists in expressing the composition of their cement products. We reveal different types of cement products, their compositions, properties, and typical uses. Wherever possible, we tend to give reasons as to why a particular cement type is more suitable for a given purpose than other types.

High Alumina Cement (HAC, sometimes known as calcium aluminate cement (CAC) or aluminous cement) is composed of calcium aluminates, unlike Portland cement which is composed of calcium silicates. It is manufactured from limestone or chalk and bauxite. Composition: The main active constituent of calcium aluminate cements is monocalcium aluminate (CaAl2O4, CaO, Al2O3, or CA in …
For this reason, even after years, the material won't change its concrete image; on the contrary the wear and tear determines an ageing completely coherent to concrete artifacts. FIRE RESISTANCE Conclad is ranked in the class A2-s1-d0 (EN13501) and Concreo in B-s1,d0, which makes them usable in total safety even in public areas.

In this article we discuss about manufacture, […]
Wet process. There are two different processes of manufacturing cement. wet process minerals are wet ground (by adding water) to form a slurry and then dried, dry process minerals are dry ground to form a powder like substance.Both the processes are in use and have their own advantages and disadvantages.While in wet process grinding is easier,in dry process there is a saving in fuel …

Concrete is considered as a chemically combined mass where the inert material acts as a filler and the binding materials act as a binder. The most important binding materials are cement and lime. Inert materials used in concrete are termed as aggregates. Most common aggregates are sand, brick chips, stone chips, gravels, shells etc. The concrete plays a very important role in all branches …

The above advantages of Portland pozzolana cement have been attributed due to the slow conversion of calcium hydroxide Ca(OH) 2 in the hydrated cement paste into cementitious product. In one of the recent studies in an ordinary Portland cement paste only 20% calcium hydroxide was found after 1 year hydration where as in a similarly hydrated paste containing 30% pozzolana, only 8.8% calcium ...

The following are the disadvantages of concrete : Due to low tensile strength, concrete is required to be reinforced to avoid cracks. In long structures expansion joints are required to be provided if there is large temperature variance in the area. Construction joints are provided to avoid cracks due to drying shrinkage and moisture-expansion.
Cement concrete is an important construction material. Its importance is increasing every day. It is a composite material consisting of a binding material, which is essentially cement, inert mineral Filler, known as aggregates and water. Thus cement concrete can be prepared by mixing above ingredients in a fixed proportion.
