The aim of the study was to determine the response of soil enzymes such as dehydrogenases, urease and acid and alkaline phosphatases to heating oil contaminating (0.0, 0.25, 0.5, 0.75, 1.0, 1.5% of soil) the experimental soil supplemented with lime and used for cultivation of yellow lupine of the Markiz variety. An increasing contamination of soil with heating oil stimulated the activity of deh...

This study was carried out to evaluate the effect of spent oil contamination on the strength of lime stabilized soil. Laterite soil was stabilized with lime in percentages of 0, 2, 4, 6, and 8% of the dry weight of soil. Specimens were prepared for UCS and CBR. The specimens for UCS were cured for 7, 14 and 28 days; while the specimens for CBR were cured for 4 days. Contamination of the specime...

textile industry is the major source of water consumption and wastewater pollution.there are various treatment techniques to remove textile wastewater pollution. coagulationflocculation is a widely used process to remove pollution due to suspended particles. in this research, different coagulants like alum, lime, fecl3, feso4 and mgcl2 were applied to select the suitable ones with optimum remov...

Lime flocculation/sedimentation in the first process unit of a 4,500-m3/day wastewater reclamation plant reduced numbers of microorganisms extensively when operated at pH 11.2. The efficiency was much less at lower pH values, and some bacteria even multiplied at pH 9.6. Data on reduction in the number of microorganisms in the lime treatment and subsequent units indicate that inactivation by hyd...

Natural hydraulic lime soil has good mechanical properties; as an earthen ruin restoration material, its durability is insufficient. Despite natural being a topic that been studied for several years from different researchers, it not yet fully considered the improvement of durability. This work aims to experimentally investigate enhancement properties lime-based. The performance limestone by ad...

The paper presents the results of testing performance lightweight structural concrete containing hemp shives as an aggregate. It has been analysed how higher binder content and use Portland cement affect thermal microbiological properties concrete. aggregates plant origin are incompatible because chemical compounds, dissolved in water or alkaline environment, inhibit hydration. To avoid this, m...

Coatings and plasters are an integral part of masonry cladding, having a fundamental protective aesthetic function. They exposed to numerous aggressive actions, which produce their degradation over time. The utilization lime, as binder in lining mortars, plays important role durability conservation. objective this work is analyze the fresh properties lime-based mortars for application restorati...

To find out which render mortar mix shows the best durability properties, we have designed four ageing tests that aim to simulate water movements, ice formation and salt crystallization in lime mortars exposed to an extreme, but realistic, range of temperature and humidity. It has been found that the response of individual mortar mixes differs according to the mechanism and the agent of attack....

BACKGROUND Fires, explosions, and extreme heat production may occur when sevoflurane reacts with desiccated barium hydroxide lime. The identity of the flammable gas has not previously been published, although carbon monoxide, methanol, formaldehyde, and methyl formate have been identified in low quantities. METHODS The authors reacted sevoflurane with excess desiccated barium hydroxide lime o...
