This concrete road is very thirsty and absorbed as soon as it falls

I think a lot of people who have read this article have had such experience. They stood innocently by the roadside but they were splashed with dirty water. Or, on rainy days, the road pits on the road will collect water, making it more difficult to drive. However, after the new type of concrete that can absorb surface moisture is widely used after road construction, unpleasant road experience will become history.

It is understood that this magical concrete is called Topmix penetrating concrete, which has super absorbent capacity and allows moisture to penetrate. It looks like the water on the ground is absorbed by a dry road instead of letting the water stay on the surface and form water.

In addition to preventing road flooding and flooding, the new type of concrete can also make road traffic more secure and avoid many traffic accidents due to puddles.

The surface of the new concrete is a permeable layer that allows moisture to penetrate large pebbles into the looser crushed stone layer.

The gravel layer also incorporates drainage channels to help drain water.

Lafarge Tarmac, a new concrete manufacturing company, said in a statement that this kind of concrete can not only prevent floods in urban areas, but also cool the roads in summer.

Penetrated concrete allows surface water to penetrate into the lower ground and can act as a reservoir during heavy rain. When the temperature is high, the evaporation of stored water can cool the ground temperature.

Penetrating concrete is not a new concept. In fact, it has been around for nearly 60 years and is often used to assist in drainage of urban road systems.

The difference is that Lafarge Tarmac developed this material so that it can also be used on the ground, and can withstand the rolling of the car.

Lafarge Tarmac stated that penetrating concrete is particularly suitable for places where water can easily accumulate, such as parking lots and private lanes. In addition, it can also be applied to bicycle lanes and sidewalks.

However, this type of infiltration concrete cannot withstand extremely low temperatures. For example, when the temperature is lower than zero, the road on which this material is laid tends to be frozen, deformed or cracked.

Lafarge Tarmac stated that the parking lot and Worksop Golf Course in the town of High Wycombe in England are now in use. In the future, there will be more and more roads using this new type of permeated concrete. However, there should be a long way to go before the global reach becomes widespread. It is hoped that the problem of being unable to withstand low temperatures before it has been adopted has been solved.

Shear Beam Load Cells

Shear Beam Load Cells are widely used where operators need to measure compressive forces. The core component of a shear beam load cell is a spring element. This element is a piece of metal that is elastically deformed under load and recovers the moment the load is removed.

The (single-ended) shear beam is designed for low profile scale and process applications. The shear beam capacities are from 100kg to 50t. One end of the shear beam contains the mounting holes while the opposite end is where the cell is loaded. The load cell should be mounted on a flat smooth surface with high-strength hardened bolts. The larger shear beam cells have more than two mounting holes to accommodate extra bolts to keep the hardware from stretching under stress load.
