What is Ready Mixed Concrete? Ready Mixed Concrete (RMC) is concrete that is manufactured in a batching plant according to a fixed mix design and then delivered to construction sites in a plastic (fresh) state using transit mixers. Instead of mixing concrete manually on site, RMC is prepared under controlled conditions , ensuring better quality and consistency. Materials Used in RMC RMC is made from the same basic ingredients as normal concrete, but in precise proportions: ·          Cement ·          Fine aggregate (sand) ·          Coarse aggregate (gravel or crushed stone) ·          Water ·          Admixtures (like plasticizers, retarders, accelerators, etc.)   Types of Ready Mixed Concrete 1. Transit Mixed Concrete ·      ...

What type of aggregates are recommended for the production of high strength concrete? What is an Aggregate in Construction? An aggregate is a broad category of coarse to medium-grained material used in construction, including sand, gravel, crushed stone, slag, and recycled concrete . Types of aggregates  There are 2 types of aggregates.  1 Fine aggregates 2 coarse aggregates For high-strength concrete, angular crushed stone  is recommended due to its rough texture, which provides superior mechanical interlocking and a stronger bond with the cement matrix.  Key recommendations for high-strength concrete aggregates: Aggregate Type/Material: Crushed stone or gravel (e.g., granite) is ideal because of its durability and strength. Shape: Angular, crushed aggregates are best for high strength. They create a better bond than rounded gravel, which is poor in interlock. Size: Smaller maximum aggregate sizes (e.g., 10 mm to 12.5 mm) are preferred as they enhance bond strength ...

Q) what is cement in construction? What is Cement? A  cement  is a  binder , a  chemical substance  used for construction that  sets , hardens, and adheres to other  materials  to bind them together.   Types of Cement Cement can be categorized into two main types – hydraulic and non-hydraulic cement.  Hydraulic cement is formed by the reaction of powdered cement with water. You can use it for all types of construction, including underwater construction projects. Non-hydraulic cement sets and becomes adhesive due to carbonation. You can use it for various construction projects, except underwater construction projects.  Hydraulic cement is the most commonly used cement. Portland cement is a type of hydraulic cement that’s been a preferred choice for architects, engineers, and constructors. The primary reason behind its popularity is its ability to harden quickly.   Ordinary Portland cement (OPC) When Portland c...
