Polyacrylamide (PAM) is a water-soluble polymer with strong cohesiveness and water absorption capacity, it has been widely used to modify soil structural stability. However, little information available on the impact of PAM application aggregate-breaking process purple soils in hilly areas southwestern China. Therefore, current study aimed examine influence aggregate stability terms different b...

Soil susceptibility to seal formation and erosion depends on its inherent properties and surface conditions. Our objective was to study the interaction of two different surface conditions, antecedent moisture content (AMC) and aging duration, on seal formation and erosion in four smectitic soils. Soil samples were packed in trays and wetted with different amounts of water (0, 1, 2, 3, 4, 6, 8, ...

The formation and stabilization of soil aggregates play a key role in soil functions. To date, few studies have been performed on the variation of soil aggregation with increasing soil weathering degree. Here, soil aggregation and its influencing factors along the weathering gradient were investigated. Six typical zonal soils (derived from similar parent materials) were sampled from temperate t...

In Tata Steel Ltd.- India, the calcined lime produced in Merz-kiln is stored respective bins for its further use steel making at LD shops. The quality of controls steel, refractory life and productivity. It also helps removing impurities during steel-making process. Longer inefficient storage results into degradation due to air slaking fines generation. To optimize time, a model has been develo...

Abstract According to various historic accounts and material evidence, the practice of producing lime mortars by mixing quicklime with sand (i.e. hot-mixing) before first slaking it water was much more common in past centuries than appreciated most contemporary academics, conservation professionals craftsmen. However, last 10 years, there has been resurgence interest hot-mixing. In such systems...

Aggregate stability is a commonly used indicator of soil health because improvements in aggregate are related to reduced erodibility and improved soil–water dynamics. During the past 80 90 years, numerous methods have been developed assess stability. Limited comparisons among resulted varied magnitudes response management practices influences inherent properties climate. It not clear whether se...

The evaluation of soil susceptibility to runoff and water erosion in the field is often expensive or time-consuming. Several authors have reported that susceptibility is linked to aggregate stability, whose determination is far easier. However, this susceptibility has generally been deduced from rainfall simulation experiments on sieved soil samples, whose behaviour is not always representative...

In the desert Southwest, communities are slaking their thirst for knowledge with an outreach program that is overflowing with environmental health information. The Southwest Environmental Health Sciences Center (SWEHSC) at the University of Arizona in Tucson is one of 21 such centers that, along with 5 Marine and Freshwater Biomedical Sciences Centers and 1 Developmental Center, make up the 28 ...
