some heavy clay soils of the A6 and A7 types with tar emul­ sions and cutbacks on an experimental subgrade stabilization during the summer of 1937, we found that this type of soil stabilization presents some very different problems from those of soil-aggregate stabilization. Soil-cement stabilization, as described by Mr. Myers, also presents some interesting problems. According to its claims, t...

Cement dust deposition on soil has been implicated in the heavy metal (HM) contamination of soil, leading to adverse effects on plants and humans. This study assessed the impact of cement dust deposition on the HM content of the soil samples in the vicinity of a cement factory and its implication on the public health of the host community. Topsoil samples were collected at varying distances and...

In past days many researchers have been worked on the stabilized Black Cotton (BC) soil to determine the Unconfined Compressive Strength (UCS) values in a conventional ways in laboratory thorough experiments, which is time consuming and requires number of persons. So we the authors of this study attempted to determine these values using Artificial Neural Networks (ANN). ANN which are simple mat...

ABSTRACT: Overall plant growth and microbial biomass can be effected by dust accumulation. The chloroform fumigation-extraction method was used to evaluating the effect of cement dust pollution emitted from Kurdistan cement factory on soil microbial biomass carbon. Chlorophyll content (a, b and total) of plants species was measured in different distance from cement factory. Mic...

The globally growing demand of cement results in towering collection of kiln dust from cement plants. The disposal of this fine dust is very difficult and poses an environmental threat. To overcome this problem, research is being carried out in different parts of the world to find out economical and efficient ways and means of using cement kiln dust (CKD) in various applications like soil stabi...

Soil stabilization has become a major issue in construction engineering and the researches regarding the effectiveness of using industrial wastes are rapidly increasing. The present experimental work briefly describes the suitability of the locally available Rice Husk Ash (RHA) to be used in the local construction industry in a way to minimize the amount of waste to be disposed to the environme...

limestone, exploited near bielawy, a town located in the kujawsko-pomorskie province ofpoland, is the main raw material in the production process in a cement plant. the dust emitted by the factory is of alkaline ph and contains such heavy metals as: cadmium (cd), lead (pb), chromium (cr) and nickel (ni). the research aims at assessing the influence of cement dust on the total content and bioava...

This paper presents the compressibility of tropical peat reinforced with cylindrical cement columns. When a cement column is installed vertically in peat, its compressibility is reduced because of the hardened skeleton matrix formed by cement particles bonding with adjacent soil particles in the presence of pore water. The effects of the cement column diameter on the compressibility have been i...

The purpose of this paper is to advance the knowledge on peat soil stabilization by critically examining and documenting the current state of practice. Deep mixing method is emphasized on column type techniques using lime/cement. This paper is essentially a comprehensive review of available academic literature on deep soil stabilization utilizing this approach. Deep mixing with lime or lime-cem...

Heavy metal mobilization in the biosphere by human activities has become an important process in the geochemical recycling of these metals. In this work, 34 soil samples and 29 Tephrosia elegans plants collected in the vicinity of the Diamond Cement Factory, Aflao, Ghana were analyzed for As, Co, Cr, Cu, Mn, Ni, Pb and Zn using energy dispersive XRF. The results of the metal analysis indicated ...
