What Are The Limitations Of Using Concrete In Construction?

Concrete is nowadays the most widely used material. Yet there are a lot of disadvantages related to it. Most of these disadvantages are due to the constituents used in the formation of concrete. Although concrete is cheap in price thus affordable and is easily available, there are adverse effects on the environment. Concrete is tried to modify by adding admixtures to it to decrease its negative impact, but it didn’t help out much. Here is how Concrete Contractors of Macon use concrete to their advantage and how they do it the right way.

1. Low tensile strength of concrete. The tensile strength of concrete is comparatively low. Whereas compression is a different phenomenon. The compressive strength of concrete is 10 times more than the tensile strength. In order to increase the tensile strength of the concrete, various polymers and fibers are used with it.

2. It has a low specific strength. The term specific strength is referred to as the ratio of strength to density. Steel is basically having double specific strength than that of normal grade concretes. It can be controlled by increasing the strength and decreasing the density. Lightweight and heavyweight concretes are lacking this property.

3. Deals perfectly with the cracks. Cracking of the concrete can be caused due to several factors. These crack results to the corrosion of concrete further damaging and causing high risks. To solve this problem, a special type of concrete is called prestressed concrete. This helps overcome the cracks …

What Are The Things That You Must Know About Concrete?

Concrete is the vitally used material in construction work. It has to be set and hardened by mixing water with it before using it. This hardness is caused due to a chemical reaction known as hydration. It helps you to bind different raw materials together. It is made by the mixing of several materials like cement, sand, stones, gravel, water, etc. All these components mix together to form a hard material. It is now the most used material made by man. It can be useful to us in making pavements, overpasses, motorways, the foundation of the buildings and houses, poles and fences, etc.

Working of cement. The different raw materials are mixed with water to make a liquid substance so that it can be molded. After setting up it in the molding casts, they become hard and rigid. In the modern world, the use of concrete has become a fact. It has various forms. One of them is porous or permeable concrete that can permeate water through it. For making such concrete, voids are entrapped in it. It has a compressive and tensile strength which helps it maintain rigidity. It is durable enough and does not easily rust or damages.

Use of concrete in construction. Concrete is an important material now and it needs high monitoring and control to improve its quality. Transport is becoming the fundamental aspect nowadays. For better concrete, we need to add less water. It will then show less permeability and high strength. Thus …

What Are The Different Types Of Concrete?

With the growing industries and technologies, the concrete industries are at the top of the competition. Concrete is the most vitally used material. It is being used in every other field, whether mitigating the pollution, or construction of houses and buildings.

There are now different types of concrete being used in the market. The various types of concrete are given different names with some unique qualities. This classification is basically based on the following factors.

1. The material that is being used in the formation.

2. The density of concrete.

3. Nature of the stress and tension.

Further, the concrete is classified as following.

1. Lightweight concrete. Concrete that is having less density is considered to be lightweight concrete. The aggregates that are used in this type of concrete include scoria, pumice, other artificial materials such as clay and shale, and other processed raw materials like vermiculite and perlite.

The most important feature of lightweight concrete is that its thermal conductivity is very low. There is a big difference between plain concrete and lightweight concrete. This concrete is brought to use depending on the composition. These are also used as building blocks.

 

2. Permeable concrete. It is prepared in such a way that water can easily permeate through it, thus the name is permeable concrete. The voids present in this concrete make it so. This concrete is mostly used in areas where stormwater is an issue.

3. Vacuum concrete. This concrete has more amount of water as …

What Are The Different Characteristics Of Concrete?

Concrete is basically a mixture of fin, coarse, and aggregated fluid cement that gradually hardens itself. Earlier, the cement binders used were such as lime putty which was common in use. Sometimes, these were brought up in use with the hydraulic cement or the Portland cement constituents. It is one of the most widely used materials for construction purposes. The usage of concrete being double of wood, steel, plastic, or any other material. But it has some adverse effects on the environment. It is the reason behind the rapid emission of greenhouse gases. But on other hand, it has a lot of benefits as it is the one that can observe the pollution released by other industries.

Some of the characteristics of concrete are discussed below.

Weight of the concrete. The unit weight of concrete is based on the amount and type of voids and aggregates respectively, and the reinforcement of it. The weight of plain concrete is less if compared.

The durability of the concrete. Concrete is the most resistant material that is used in the construction of buildings and houses. It does not detour away over a long period of time. The main reasons behind the deterioration of concrete include the use of cheap constructing raw materials, environmental causes, temperature, moisture, humidity, chemical, physical and biological factors, etc. but the concrete is permeable enough to resist these factors. This permeability gets affected due to the irrational mixing of raw materials used in manufacturing.

Strength of
