Abstract: This paper is about an experiment which should prove that slaked lime is suitable as an ecological moisture retardant. Therefore, the performance of straw, sheep wool, hemp and directed hemp covered with slaked lime was monitored over a long period. The other half of the probes were uncovered to serve as reference data. The main focus of this experiment is to determine the moment when the probes start to mold as extreme humidity in reality only lasts for a short time. During the experiment the used material is continuously exposed to moisture whereas under non-experimental conditions exposure to moisture would last for a much shorter period of time (cooking, cleaning, etc.) This paper only covers the performance of straw and sheep wool covered with lime. Also the spreading of mold will not take place.

Abstract: Studies have been conducted to investigate biomass accumulation of earthworms (Eisenia fetida andrei), cultivated in the soil media under various concentrations of the slaked lime. The group, which is cultivated on the media with lime concentration 0.1% is characterized by maximum biomass accumulation (average – 120 %). As a result we have discovered two phase kinetic dependence between biomass accumulation of earthworms and the amount of the slaked lime.

Abstract: Slaked lime is a suspension of hydrated lime in water that can contain up to 40% of solids in suspension. The quality of the suspensions of slaked lime depends on the quality of lime used and on a careful choice of the conditions during the hydration process. A high quality slaked lime is a product with a small quantity of insoluble residues, high specific surface area, high alkaline content and small particle size. Therefore, the objective of this work was to study the best conditions of temperature and concentration to produce a superior slaked lime. A statistic analysis was performed using the experimental results in order to optimize the operational conditions of the hydration process. The use of hydration water around 74 °C, of small particles of CaO (0.144 mm) and of a CaO/H2O ratio around 220 g/L contributed to the production a slaked lime suspension of fine quality.
