Attenuation is an important consideration in the modern world of wireless telecommunication. Attenuation limits the range of radio signals and is affected by the materials a signal must travel through (e.g., air, wood, concrete, rain). See the article on path loss for more information on signal loss in wireless communication.

Spectral Reflectance

Water has high absorption and virtually no reflectance in near infrared wavelengths range and beyond. Turbid water has a higher reflectance in the visible region than clear ...

The effect of cement paste volume and w/c ratio on shrinkage

To test water absorption and compressive strength, 10 cubes 10x10x10 cm of each concrete were cast, cured in water for 28 days and tested. Water absorption tests were performed to PN-EN 13369:2013-09 on 5 cubes of each concrete. After wiping off the water, the specimens were weighed and dried 7 days at 105 °C.

capillary absorption of concrete after being subjected to uniaxial compressive or tensile loading by a series of water absorption experiments (three load levels: 70%, 80% and 90%). They found that the rate of capillary absorption load-damaged concrete is approximately double of sound concrete within the scope of load level studied.

Compressive Strength of Jordanian Cement Mortars

It has been concluded that the compressive strength and its development with age has some variations between the different cement brands. There is an inverse linear relationship between compressive strength and water absorption, and a weaker positive relation with density. There is no clear relation between consistency and compressive strength.

Absorption characteristics of metakaolin concrete

Water absorption (WA) by total (shallow) immersion is generally measured by drying a specimen to constant mass, immersing it in water for a specific time and measuring its increase in mass as a percentage of the dry mass. Capillary water absorption of concrete, however, is the phenomenon by which water is absorbed into concrete by capillary action.

Exp 3 & 4 Specific Gravity & Water Absorption

Water absorption is a measure of porosity of aggregates and its resistance to frost action. Higher water absorption means more pores hence aggregate will be the considered as weak. Water absorption value ranges from 0.1 – 2.0% for aggregate normally used in

Absorption Refrigeration System, Cycle, unit, how does it Work?

In the vapor absorption system the refrigerant used is ammonia, water or lithium bromide. The compressor is replaced by the absorber and the generator in the absorption refrigeration system. Another major difference between the vapor compression and vapor absorption cycle is the method in which the energy input is given to the system.

Types of concrete

Pervious concrete, used in permeable paving, contains a network of holes or voids, to allow air or water to move through the concrete This allows water to drain naturally through it, and can both remove the normal surface-water drainage infrastructure, and allow replenishment of groundwater when conventional concrete does not.

Shrinkage in Concrete, Definition, Types, and Factors

Concrete shrinkage of this type manifests itself soon after the concrete is placed in the forms while the concrete is still in the plastic state. Loss of water by evaporation from the surface of concrete or by the absorption by aggregate or subgrade, is believed to be the reasons of plastic shrinkage. The loss of water results in the reduction ...

Attenuation coefficients

2. Linear attenuation coefficient. The coefficient μ must have the dimension of length-1. It is called the linear attenuation coefficient. It is generally expressed in cm-1. The linear attenuation coefficient μ is defined as the fraction of an incident beam of photons that is absorbed or scattered per unit thickness of the target absorber.
