The Importance of Concrete Slurry Clean Up

June 22, 2017

Concrete work is part of City life. Out among the long grasses and grazing livestock of a rural setting, more concrete structures appear seemingly overnight. No one takes issue with these construction ventures. Similarly, there are no misgivings when concrete foundations are laid for new housing complexes. But what about the concrete slurry, the byproducts that accompany these constructions? Can this grey muck be allowed into a drainage system?

Gritty Concrete Characteristics

This is a construction material that holds solid when it's pressed into place, but that substantialness collapses when it mixes with water. The gritty material tends to lay suspended when it blends with water, at which point its various chemical compounds are leached into the groundwater. Concrete washout, the material that flows in the slurry, contains hard aggregates and limestone, plus small quantities of heavy metals. If you're visualising the effects of those compounds on the environment, try picturing aggregate choking and alkaline runoffs. Additionally, heavy metal oxides are trapped inside the murky stuff, so that mixture is indeed loaded with hazardous chemicals.

Correctly Cleaned Concrete Slurry

First of all, the slurry should never be left to its own devices, so it mustn't be allowed to access the local stormwater drainage system. Left to do so, that chemical soup will enter the water supply and impact the environment. Granted, construction gear has to be washed down at the end of the day but not into a guttered network that connects to potable water. Instead, the material must be properly cleaned up and contained. The aggregate, now no longer clogging the drains, is filtered and recycled. Likewise, the sand and concrete particulates are filtered and reused. Airborne particulates are another matter, of course, for these clouds tend to settle like a fine cloud of dust. Vacuum cleaning gear will collect the dusty remains, store it, and deposit the mountains of dust into aggregate bins.

As the importance of concrete slurry clean-up has unfolded, you've gained an insight into how corrosive this building material can be if it's left to accumulate on the ground like sand. Whether you're looking at concrete, stucco, cement, or asphalt, each of these aggregate mixes is loaded with environmentally hazardous compounds. If they do somehow make their way into the water supply, aquatic habitats are in danger, and your own drinkable water could become contaminated. Contain the aggregate and its binding compounds. Recycle the grit, filter the murky water, and vacuum the dust.
