Category: CONCRETE

Reinforced cement concrete is a topic you will need to familiarize at some point, if you are into civil engineering field. The category explicitly presents it. Reinforced cement concrete (RCC), a composite material has been accepted worldwide as a construction material, bridges, retaining walls, docks and harbour, airfield pavements, flyovers,multi-storey building,complexes and simple houses etc., Concrete is good in resisting compression but is very weak in resisting tension. Hence reinforcement is provided in the concrete wherever tensile stress is expected. The best reinforcement is steel since the tensile strength of steel is quite high and the bond between steel and concrete is good. As the elastic modulus of steel is high, for the same extension the force resisted by steel is high compared to concrete. However in tensile zone, hair cracks in concrete are unavoidable. Reinforcements are usually in the form of mild steel or ribbed steel bars of 6 mm to 32 mm diameter. A cage of reinforcements is prepared as per the design requirements, kept in a formwork and then green concrete is poured. After the concrete hardens, the formwork is removed. The composite material of steel and concrete now called R.C.C. acts as a structural member and can resist tensile as well as compressive stresses very well. Aggregates are the inert or chemically inactive materials which form the bulk of cement concrete. These aggregates are bound together by means of a cement. They can be classified into two. The selection of aggregate is based on the purpose and its maximum size.

Concrete Compressive Strength Formula: A Comprehensive Guide

Vinod Gopinath

The concrete compressive strength formula is fundamental. It calculates how well concrete can resist axial loads without failing. Concrete compressive strength formula is crucial for determining the strength of concrete structures. It also ensures the durability of buildings, bridges, and roads. The formula for concrete compressive strength is expressed as fc = P/A. Here, P is the applied load. A is the cross-sectional area of the concrete specimen. To ensure accuracy, concrete compressive strength testing methods follow strict guidelines.

Self Compacting Concrete (SCC)-Ingredients and Advantages

Vinod Gopinath

Self-Compacting Concrete (SCC) is a high-performance, self-leveling concrete that flows effortlessly without external vibration. It improves workability, reduces labor costs, and enhances structural quality. Its advanced mix design includes aggregates, cement, and superplasticizers. SCC is ideal for complex structures and offers durability, sustainability, and efficient placement techniques. Enhanced performance trends continue through ongoing research.

As a construction material, concrete should be able to withstand heavy loads. The concrete material beneath compression tends to reduce its size. Concrete gains its strength over time. The compressive strength depends on cement strength, water-cement ratio, concrete quality etc. The test gives an idea of the overall strength and above-mentioned factors.

Pervious Concrete- All Factors Affecting, Limitations and Methodology Explained

Vinod Gopinath

Pervious concrete pavements (PCP) are advancement of innovative materials that contribute to the construction of better structures. We will find out the basic and technical details, design considerations, factors affecting the performance and limitations of PCP in the blog. Pervious concrete is a special form of concrete with a high porosity used for concrete flatwork applications that allows direct passage of precipitation water and other sources, thereby reducing the runoff from a site and allowing groundwater recharge.

Reactive Powder Concrete- 6 Components and All Properties Explained

Vinod Gopinath

Reactive Powder Concrete (RPC) is a type of Ultra High Performance Concrete (UHPC). The main constituents are cement, sand, silica fume, steel fiber and quartz powder with minimal water to binder ratio, without coarse aggregate. In RPC, water- binder ratio is very low, CA is absent- reduce the heterogeneity of concrete mix and optimize microstructure. Precise gradation of particles yields compact, well-arranged and high strength hydrates of maximum density.

CONCRETE, Water Cement Ratio

Water to cement ratio – An Important Strength Factor.

Vinod Gopinath

Water to cement ratio is the ratio between the weight of water to the cement weight used in a concrete design mix. The water to cement ratio can significantly impact the workability and strength of the concrete.
