Top Procedures in Cement Concrete Construction
One of the most used man made material is the cement. Buildings and other structures requires cement in their construction. Cement, sand, water and gravel are the materials that make up concrete. Cement is major requirement in the manufacture of concrete. In the presence of water, cement is used in joining together gravel and sand.
Concrete made up of reinforcement bars is refereed as reinforced cement concrete. Steel and cement are good materials in holding the concrete together because they are very strong and they can be acquired at a cheaper price. To achieve high quality concrete, there are certain steps and procedures which must be followed.
It is good to determine the ingredients needed and their amounts and proportions. These proportions include the type of cement, the type of aggregate and its size, the water amount, chemical mixtures. To have a concrete that generates good results it is important to establish this requirements. After getting the ingredients in place, it is now essential to determine the most appropriate design mix. Economic factors should be considered whilst evaluating the needed properties of the concrete. The strength of the concrete must be ensured though ensuring the utmost support of the load. Workability can be explained as the ability of the concrete to spread out when put on a flat surface.
It is import to consider the concrete environment. The environment should not lead to freezing and melting up of the concrete. There should be resistance to moisture and harsh soil elements. In order to meet the intended purpose and lasting long, the surface should not easily wear out.
Once the ingredients are in place and the necessary considerations are made, then it is time to mix. The contractor should not under mix the ingredients because it leads to weaknesses.
Pouring is a method under placing which is done if the mixing site is near the construction site. Trucks are used to transport ready mix under long distances but under short distances, buckets and cranes are used. To clear any air gaps, consolidation is done. The compacting by rollers should be done carefully and should not be overdone. Finishing is the second last activity of cement concrete construction and it involves adjusting the appearance of the concrete which can be the floor in this case. Letting the concrete cure enables reduction of vulnerability of the surface.
