In this work, the effect of chitosan and CaCO3 coating on polyurethane (PU) foam on the mechanical and thermal properties was studied. PU-foams were soaked in a mixture of chitosan- calcium carbonate solution at different concentrations, i.e., 0.1–0.4%. T... see more

Calcium carbonate (CaCO3) plays a crucial role in influencing the growth of osteoblast. This study was conducted to compare the performance of alginate/cockle shell powder nanobiocomposite (nCP) bone scaffold developed from naturally occurring CaCO3 with ... see more

The results of a study that assesses the effect of adding small amounts of calcium carbonate as fluxing agent on fired Clay bricks are presented. The paper aims to improve the energy demand of fire clay bricks manufacture through the reduction of firing t... see more

Phenolic compounds are secondary metabolites synthesised in response to biotic or abiotic stress in plants.  This stress-induced increase in phenolic compound concentrations is generally activated by internal levels of abscisic acid (ABA). The exogen... see more

the invention provides for study properties of polypropylene (injection grade) / polypropylene (extrusion grade) blend filled with calcium carbonates. In four formulations of PP(Injection grade)/PP(Extrusion grade)) viz. 95/5, 90/10, 85/15 and 80/20 in ra... see more

In this work the effects of different crystallographic modifications of calcium carbonate (CaCO3) filler on the melt flow, mechanical properties, hydrolytic degradation, and shape memory behaviour of recycled low-temperature poly(e-caprolactone)-based pol... see more

Attempts have been made to evaluate four methods of quantitative determination of soil carbonates. Calcium carbonates equivalent were determined by the acid neutralization, calcimeter and acetic acid methods. Also, it obtains by the fourth methods when th... see more

Concrete is the most widely used construction material in civil engineering. But plain concrete is a brittle material and has little resistance to cracking. The cracking in concrete promotes deterioration such as the corrosion of reinforcing rebar, theref... see more

Hypocalcemia is one of manifestation of bone metastases which could be treated  using calcium carbonate and cholecalciferol. Tc-99m radiolabeled 1,4,8,11-tetraazacyclo tetradecyl-1,4,8,11-tetramethylene phosponic acid(against 99mTc-CTMP)on the other ... see more
