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

Types of Concrete

Reinforced concrete was developed to add the tensile strength of steel to the compressive strength of mass concrete. It was invented (1849) by Joseph Monier, who received a patent in 1867.

Precast-concrete construction, employs bricks, slabs, and supports made under optimal factory conditions to increase waterproofing and solidity, to decrease time and cost in erection, and to reduce expansion and contractions

Prestressed concrete provides bearing members into which reinforcement is set under tension to produce a live force to resist a particular load. Since the member acts like a spring, it can carry a greater load than an unstressed member of the same size.

Tilt-up Construction and Tilt wall: What is the Difference ?

For a tilt-up concrete building, the walls are created by assembling forms and pouring large slabs of cement called panels directly at the job site. The cement panels are then tilted up into position around the building's slab to form the walls. Tilt-up concrete panels have been measured at just over 69 feet across and almost 93 feet from top to bottom doing this architects have a flexibility in planning to create their buildings. For other hand the architect that use tilp-up walls need to be aware of climatic conditions.


The concrete tiltwall forms are assembled and poured directly at the job site, no transportation of panels is required. One major benefit of this is that the size of the panels is limited only by the needs of the building and the strength of the concrete panels themselves.


The precast concrete building process is similar to tilt-up construction. For precast concrete buildings, work crews do not set up forms at the job site to create the panels. Instead, workers pre cast concrete panels to make it easy to work with.This is way it doesn't matter about weather conditions, then thiese panels are taken to the job site and then assembled like tiltwall. this invention are created to resolve weather problems.
