CONCRETE WORKS Plain and Reinforced Concrete Plain Concrete o an artificial stone as a result of mixing cement, fine aggregates, coarse aggregates, and water. Reinforced Concrete o Is a concrete with reinforcement properly embedded in such a manner that the two materials act together in resisting forces. CONCRETE WORKS Different Types of Concrete Used in Construction are: 1. Ordinary Portland Cement 2. Rapid Hardening Portland Cement which is preferred when high early strength concrete is desired 3. Blast Furnace or Sulfate Cement used on concrete structures designed to resist chemical CONCRETE WORKS Different Types of Concrete Used in Construction are: 4. Low Heat Portland Cement used for massive sections designed to reduce the heat of hydration 5. Portland Pozzolan Cement with a low hardening characteristics concrete 6. High Alumina Cement CONCRETE WORKS Aggregates 1. Coarse Aggregate • such as crushed stone, crushed gravel or natural gravel with particles retained on a 5 mm sieve 2. Fine Aggregate • Such as crushed stone, crushed gravel, sand or natural sand with particles passing on a 5 mm sieve CONCRETE WORKS Concrete Proportion MASONRY WORKS Concrete Hollow Blocks Concrete Hollow Block is popularly known as CHB. It is classified as load bearing (15 – 20 centimeters thick) and non-bearing blocks (7-10 centimeters thick). MASONRY WORKS Concrete Hollow Blocks Concrete Hollow Block is popularly known as CHB.
