Magnesium Phosphate Cement: Characteristics and Advantages
Magnesium phosphate cement (MPC) hardens rapidly and gains high strength in a short time, ranging about several hours to the level of normal strength of ordinary Portland cement concrete. The magnesium phosphate cement binder is produced from the reaction between ...
Radiographic Evaluation of Concrete
Radiographic evaluation of concrete involves the use of radiographic test on building elements to examine the internal condition of concrete. This test is capable of examining concrete members without causing any damages. It determines the location of reinforcing steels, voids ...
Compounds in Cement and Their Influence on Concrete Strength
Compounds in cement mainly are tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium alumino ferrite. Not only do these compounds control most of cement properties but also reacts with water to produce new materials (cement hydration) and consequently responsible for ...
Cold Weather Concreting: Guidance, and Strategies
Cold weather concreting is the process of placement, finishing, curing, and protection of concrete during cold weather, as per ACI 306.1. The cold weather occurs when the average outdoor temperature is below 4.4C (40F) for more than three successive days. ...
Roller Compacted Concrete: Properties, Advantages, and Applications
Roller-compacted concrete (RCC) is a concrete of zero-slump consistency in its unhardened state used in pavement and dams. It is transported, placed, and compacted using earth and rockfill construction equipment.
What is Fire Resistance of Concrete? Mechanism and Factors
Fire resistance of concrete is the ability of concrete to withstand fire or to give protection against fire. This involves the ability of concrete structural element to continue perform a specific structural function or confine fire or both. The duration ...
What is Poisson’s Ratio of concrete?
Poisson’s ratio of concrete is the ratio of transverse strain to longitudinal strain in concrete specimen subjected to axial loads. The longitudinal strain and vertical strain are produced due to concrete volume reduction under compression load. Volume reduction of concrete specimen ...
