To control or mitigate dust, chlorides need moisture to work effectively so it works better in humid than in arid climates. As the humidity increases the chloride draws moisture out of the air to keep the surface damp and as humidity decreases it diffuses and releases moisture.
A 1,300,000-square-foot (120,000 m 2) complex of mixed residential, office, retail and commercial space is being built on 15 acres (61,000 m 2) of former industrial land in downtown Victoria that was contaminated by lead. 10 tonnes of soil was treated with cement, which was mixed into the soil on site simply by using an excavator bucket. The ...
Soil cement mixtures differs from Portland cement concrete in the amount of paste (cement-water mixture). While in Portland cement concretes, the paste coats all aggregate particles and binds them together, in soil cements the amount of cement is lower and therefore there are voids left, and the result is a cement matrix with nodules of ...
Concrete dust released by building demolition and natural disasters can be a major source of dangerous air pollution. The presence of some substances in concrete, including useful and unwanted additives, can cause health concerns due to toxicity and (usually naturally occurring) radioactivity. [4]
The deep soil mixing columns are typically 0.6 to 2.4 m in diameter and depths of up to 50m can be reached depending on the nature of the ground conditions and the technique employed. [1] Steel reinforcement can be inserted into fresh soil-mix to increase bending resistance of deep soil mixing columns used for excavation control. [2]
Resperion is a company based in Scottsdale, Arizona that is involved in the creation and development of a variety of products used in road construction, soil stabilization, dust control, and natural paving alternatives. The company's main focus is on the modification of asphalt with its IntegraBase product. IntegraBase alters the chemical ...
Dust abatement refers to the process of inhibiting the creation of excess soil dust, a pollutant that contributes to excess levels of particulate matter. Frequently employed by local governments of arid climates such as those in the Southwest United States , dust abatement procedures may also be required in private construction as a condition ...
Synthetic polymers began replacing other chemical binders for soil stabilization in agriculture in the late 20th century. [1] Compared to traditional chemical binders, polymer soil additives can achieve the same amount of strengthening at much lower concentrations – for example, mixtures of 0.5-1% of various biopolymers have strength levels that match or exceed those of 10% cement mixtures ...
