Understanding Relative Humidity in Concrete | Giatec

Even though your concrete may look dry on the surface, that doesn't necessarily mean it is dry throughout. There may still be sources of water within your concrete in the form of relative humidity. According to ASTM F2170, when drying, concrete slabs have lower moisture levels near the surface and higher levels towards the bottom of the slab.

Cathodic protection in reinforced concrete structures

Cathodic protection is a technique that has been used to control corrosion and increase the service life of reinforced concrete structure. Standards as EN ISO 12696 give protection criteria for both impressed current and sacrificial anodes techniques, based on potential value or decay during a depolarization sequence. The polarization (current ON) and depolarization (current OFF) is

Shotcrete - Unionpedia, the concept map

Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.

The History Of Concrete and How Concrete Was Invented

Reinforced concrete was invented in 1849 by Joseph Monier. He was a Parisian gardener who made garden pots and tubs of concrete reinforced with an iron mesh. He patented this concept in 1867. Reinforced concrete combines the tensile (bendable) strength of metal with the compressive strength of concrete to withstand heavy loads.

Modeling Punching Shear Capacity of Fiber-Reinforced

This study investigates an adaptive-weighted instanced-based learning, for the prediction of the ultimate punching shear capacity (UPSC) of fiber-reinforced polymer- (FRP-) reinforced slabs. The concept of the new method is to employ the Differential Evolution to construct an adaptive instance-based regression model. The performance of the proposed model is compared to those of Artificial
