Concrete

‍Concrete is a manufactured mixure of cement and water, sand and stones. Concrete is a "stonelike" water and fire resistent solid of great compressive but low tensal strenght. //Advantages:// //Disadvantages://
 * Concrete **
 * Economical substitute of traditional materials
 * Waterproof and fireproof
 * Not expensive
 * Strong in compression
 * Molds to any shape
 * Can brake with changes of temperature
 * It weighs a lot and this makes it difficult for transportation.

Concrete: Is a manufactured mixture of cement and water, with aggregates of sand and stones, which hardens rapidly by chemical combination to a stone like, water-and-fire-resisting solid of great compressive but low tensile strength.



What is the difference between tiltwall construction, tilt-up panel construction and pre-cast concrete construction?

In a Tilt-up construction project, the building's walls are poured directly at the jobsite in large slabs of concrete called tilt-up panels or tiltwall panels. In a pre-cast concrete construction walls are also directly poured at the jobsite but in large slabs or bricks.
