Abstract:
L’utilisation de Supplementary Cementitious Materials (SCMs) en substitution du clinker est une technologie aujourd’hui bien connue qui permet de réduire le coût environnemental du ciment. Parmi les SCMs largement utilisés on retrouve les cendres volantes, les laitiers de hauts fourneaux ou encore la poudre de verre. Dans les dernières années, un intérêt grandissant s’est développé pour l’utilisation d’argiles calcinées comme ajouts cimentaires, notamment du fait de leur forte réactivité et leur grande disponibilité.

Abstract:
Portland cement manufacturing process consumes large amount of natural resources and generates approximately 5% of global CO2 emissions. Consequently, alternative approaches for CO2 reduction are an important cement industry focus. The present project revisits lime-­‐pozzolan systems, as a modern approach to sustainable cement technology. The idea of the partial calcination of limestone to produce core-­‐shell like lime for blending with pozzolan is proposed. The partial calcination of limestone has been studied in an experimental fluidised bed reactor. The calcination conditions, including re

Abstract:
Due to the modernization of the construction industry, the use of waste is an attractive trend with high potential for many researchers. The majority of the waste materials that are recycled to produce new construction materials are usually by-products obtained from a variety of several manufacturing processes, such as the aggregate washing process. Recycling these materials is of utmost importance since it could reduce the adverse environmental impacts resulting from landfilling. The concept of producing asphalt mixes with waste materials serves as a way to reduce the enormous volume of waste

O presente trabalho visou estudar, em condições de casa-de-vegetação e de campo, a eficiência agronômica de misturas de calcário dolomítico calcinado e gesso agrícola em comparação com cada um dos dois produtos aplicados separadamente. Para tal, foram usados solos ácidos com diferentes características químicas a saber: Um Podzólico Vermelho Amarelo (PVA) de Capão Bonito (SP); um Latossolo Vermelho Escuro textura média (LEm) de Sorocaba (SP); um Latossolo Roxo (LR) de Itapeva (SP). Sob condições de casa-de-vegetação a planta teste foi milho, soja e trigo. As misturas de calcário dolomítico calc

Abstract:
Background & Objectives: High levels of HSP70 appear to have atheroprotective effect. It was reposted, that antibodies to HSP70 were increased in patients with vascular disease. Also HSP70 levels correlate with lesion severity. Aim of the investigation was to study the HSP70 expression in aortic tissue with calcifications affected by atherosclerosis.

Abstract:
In this thesis, the effect of dissolution on the chemistry and structure of perforate planktonic foraminiferal tests was investigated. Atomistic simulations were undertaken to study the energetics of magnesium ions in calcite and their structural ordering in the {104} surface. Shell mass, δ<sup>18</sup>O<sub>c</sub> and Mg/Ca measurements were obtained on core-top tests of foraminifera from depth transects in the Indian and Pacific oceans. The degree to which dissolution biased the temperature determined from δ<sup>18</sup>O<sub>c</sub> and Mg/Ca measurements was found to be similar for <i>G.

As alternative raw materials are used expanded perlite Vapex, calcined diatomite Celite and powder waste glass of fluorescent lamps. In the theoretical part is summarized knowledge from completed studies dealing with the issue of compensation porous filler component. In the experimental part is tested consistency of fresh mixture, physical-mechanical, sorption and thermal insulating characteristics.

Abstract:
Calcium carbonate, calcite, and magnesium carbonate, magnesite, form a series of solid solutions with compositions ranging 0 to 50% magnesite which is dolomite the end member of the series. The calcite magnesite solid solutions are called magnesian calcites (Mg-calcites). Mg-calcites exist in nature, in soils, in marine skeletal materials, in some marine cements, etc., and their existence has been associated with the supersaturation of calcite in sea water and the soil solution of some calcareous soils. They are clearly more soluble than calcite, but their chemical properties has not been defi
