Steelmaking slag is a by-product of steel making. It has been reused as a material for civil engineering, pavement construction etc. For such applications, it is extremely important to evaluate the amount of free lime, which has the chemical form of calcium monoxide (CaO) and can cause the failure of mechanical properties by volume expansion through absorption of water or carbon dioxide gas. So...

Tadpoles of Rana catesbeiana were exposed to different levels of environmental hypercapnia. The acid-base regulatory response differed from that in adult amphibians in showing a high degree of pH compensation in the extracellular fluid (65-85%) and complete compensation in the intracellular fluid (tail muscle and liver) within 24 h. Hypercapnia induced a massive transfer of HCO3- equivalents an...

BACKGROUND: In addition to controlling sediment phosphorus in aquatic systems, lime (CaCO3 and Ca(OH)2) applications have been shown to be effective in both suppressing submersed macrophyte growth and changing species composition in a variety of ponds, small lakes, canals, and dugouts (Babin et al. 1992; Chambers et al. 2001; Prepas et al. 2001a, 2001b). The mode of action for controlling growt...

INTRODUCTION Excessive soil acidity is known to have potential negative impacts on crop production. The chemical and physical characteristics of a liming material determine its capacity to neutralize soil acidity. The calcium carbonate (CaCO3) equivalent (CCE) and estimates of particle size impact on the efficiency at increase soil pH are considered when assessing a material’s liming value. The...

The transformation of CO2 into a precipitated mineral carbonate through an ex situ mineral carbonation route is considered a promising option for carbon capture and storage (CCS) since (i) the captured CO2 can be stored permanently and (ii) industrial wastes (i.e., coal fly ash, steel and stainless-steel slags, and cement and lime kiln dusts) can be recycled and converted into value-added carbo...

For characterization of the ability of crops to reflect changing soil properties after the addition of ameliorative materials into the soil both pot and rhizobox experiments were provided. In the pot experiment, the influence of the addition of lime and limestone into contaminated Cambisol containing 7.14 mg Cd/kg, 2174 mg Pb/kg, and 270 mg Zn/kg on element availability for spring wheat was tes...

A study was conducted to evaluate the effects of liming on chemical properties of wheat field soils and yield of wheat in Ranisankail soil series of Bangladesh. There were eight treatments of liming material applied from dolomite (CaCO3.MgCO3). Yield and yield components of wheat were recorded at harvest and the grain and straw were analyzed for P, S, Ca and Mg contents. The post harvest soils ...

Reducing iron solubility in calcareous soils causes iron chlorosis symptoms in the plant. In order to investigate the response of M. scutellata to direct and indirect iron deficiency, a factorial experiment was conducted in a completely randomized design with three replications. The experimental factors included three levels of lime (0, 4 and 8%) and five levels of Fe (0, 5 and 10 mg Fe Kg soil...

In the history, different mortars compositions have been used during ages in masonry structures. Lime was frequently adopted past. summary, there are two main types of lime: hydraulic and non-hydraulic (aerial). The present review deals with second type. Herein, studied lime is specially obtained from thermal decomposition, called calcination, limestone (calcium carbonate (CaCO3). Aerial a comp...

Blueberry (Vacciniumcorymbosum interspecific hybrids) production in soilless substrates is becoming increasingly popular. Soilless have low pH buffering capacity. plants preferentially take up ammonium, which acidifies the rhizosphere. Consequently, where blueberry are grown exhibit a tendency to get acidified over time. Agricultural lime (CaCO3) commonly used raise soil and substrate other cro...
