Abstract: Ridge culture is a special conservation tillage method, but the long-term influence of this tillage system on soil aggregate-size stability in paddy fields is largely unknown in southwest of china. The objectives of this paper are to evaluate soil aggregates stability and to determine the relationship between SOC and soil aggregate stability.Soil samples at 0-20 cm layer were adopted ...

The rheology of lime binders, which is critical in the final performance of lime mortars and plasters, is poorly understood, particularly in its relationship with the microstructure and colloidal characteristics of slaked lime (Ca(OH)(2)) suspensions (i.e., lime putties). Here, the contrasting flow behavior of lime putties obtained upon slaking (hydration) of soft and hard burnt quicklimes (CaO...

Abstract It is believed that many historic mortars were made using hot-lime mixing techniques. They are back in use today, and their good qualities often praised, including being more compatible a better match with fabrics. This paper studies the methods of producing putties. discusses variables determine properties resultant such as slaking calcination, compares equivalent putties, factory-pro...

The flat pampas in the state of Santa Fe in Argentina have soils with high silt content, variable carbon content, and diverse degrees of structural degradation. Aggregate stability has been used as an indicator of the structural condition of the soil. This study aimed to quantify the effect of the addition of crop residues and root activity on the agents of aggregation and mechanisms of aggrega...

Organic compounds, often used in cement systems as admixtures, may affect the crystallisation and carbonation kinetics of Ca(OH)2, an important phase hydrated cement. Here, we investigated changes Ca(OH)2 morphology presence 3 organic commonly encountered lime-based materials: sucrose, pectin calcium lignosulfonate. The additives were introduced either before or after lime slaking to determine ...

a research program was conducted on different clay-bearing rocks selected from the ilam, sarpol-e zahab and tajarak regions (iran) to predict their slaking characteristics. the new durability apparatus (nested mesh drums) separates disintegrated particles varying from > 25.4 to < 2 mm as the drums were rotated. on the basis of the particle size distribution, the disintegration ratio (dr) was us...
