Fine and coarse aggregate are fundamental requirements for construction. Sand is the superior choice of fine aggregate for the preparation of mortar and concrete and it also plays a vital role in the mix design. In developing countries such as India, there’s a greater demand for sand because of the rapid growth of infrastructure. The grading and maximum size of aggregates are critical parameters in any concrete mix as they affect the relative proportions in mix, workability, economy, porosity, and depreciation of concrete.
We have been talking about the pros and cons of steel and concrete as a construction material. Let’s get a better understanding on why they work better together. Anyone reading about construction materials would have come across the saying – Concrete is good against compression, but weak in tension whereas steel bars are good in tension, but weak in compression. What a few had inferred from the statement is that, steel is naturally weak in the face of compressive forces, which is not the case. Steel is good in both compression and tension. Steel bars or steel reinforcement bars are weak in the face of compressive force due to their dimensional property. Steel reinforcement bars have an insignificant cross sectional area when compared to the length of the steel bars, and thus the ability to withstand compressive forces are naturally less.
The construction of a commercial or residential building cannot be imagined without the use of concrete and steel. These two components are the most essential composite in the construction field. The reasons why they are preferred is their advantages in terms of strength and withstanding the loads. However, what if a comparison was made between concrete and steel. To see which one tops the other in terms of certain parameters.
So, which material surpasses the other in the field of construction – concrete or steel?. We know that both are important for constructing a structure but let us find out what these two materials are capable of.
Summer season is all over us. The temperatures are soaring high all across India, marking the arrival of the summer season in full force. The temperature has crossed 40°C in many areas. Also similar to the rising temperature, another thing that is also rising is the construction of buildings. As we know excessive heat is not good for the people involved in the construction, well it is the same case for the buildings. More specifically, the setting of concrete.
Concrete is the most vital material in the construction of buildings. There is no need for any sort of familiarization for us. It is right around us, buildings, roads, bridges, etc, all these structures are made with concrete. It is impossible to imagine a structure without concrete. The use of concrete has a long way back since ancient times. The arrival of concrete drastically changed the course of architecture in the world.
Concrete and steel are the two most vital components for the construction of a building. Concrete is known for its impressive compressive strength but it lacks the tensile strength. This tensile strength is provided by using reinforced steel bars. So both these components are needed for the construction. However, with the rise of technologies, different variants of steel, concrete etc have been introduced. One such material is Prestressed Concrete.
The last blog described the universal problem affecting the RCC which is corrosion / rusting and what are the causes of corrosion. In order for a Reinforced structure to have corrosion, the presence of these two components is needed which is moisture and air. Usually, corrosion starts out slowly and results in severe damages which in turn affects the structural integrity of the building.
Thermo Mechanically treated steel bars created the current standard of reinforcement. Their excellent tensile strength and ductility make them ideal and preferred for construction of building structures. Building structures are always susceptible to environmental changes. No building will ever be the same once the environmental changes kick in. Out of all the changes, the most serious and devastating is corrosion.
A home is dream of the common man, the common man wants a personal space where he or she unwind and relax without a care in the world. So, the common man wants a home which confines to his sense of design, safety and longevity. To meet the expectations and demands of the ever more demanding common man, the construction sector has always been in the business of reassuring people about the quality and safety of their products. Below are some of the individual raw materials which have changed the landscape of the real estate sector india.
