Physical and Chemical Properties for Stabilized Sand Using Cement Kiln Dust

Abstract

Cement kiln dust (CKD) produced in a local cement production plant in Assiut Cement Company-Egypt, along with CKD resulting from combustion of cement were utilized as waste materials. These blends were tested for their water requirements for normal consistency, initial setting times, compression and tensile strengths. The materials used in this research are ``untreated'' CKD. It was collected from electrostatic precipitators and ordinary Portland cement (O.P.C). Several specimens were prepared in the laboratory for the compressive strength testing. The specimens were prepared by proportioning sand and CKD according to selected ratios then adding the optimum percentage of water

“…Recently, there are many industrial applications for CKD. In Egypt, many authors used CKD in many applications such as removal of heavy metals, 14 recycling back to the manufacture of ordinary Portland cement, 15 to stabilize sand, 16 removal of acid dyes, 17 chemical stabilization of expansive soil, 18 an amendment for the sandy soils, 19 to modify the engineering properties of clay–silt soil materials, 20 in the production of some “green” cement products 13 . Cement dust is considered as a harmful by‐product of the cement industry that is dumped in nearby open surface impoundments or landfills.…”

Mechanical Properties of High Density Polyethylene/Cement Kiln Dust Composite Natural Monomer

“…Cement industry as many industries produce waste (solid, liquid, gas) which caused environmental pollution, in cement production a solid waste accumulated has negative impact on environment, air, water and land [1]. Although, for several years dramatic advances have been achieved in waste solid management and use of cement kiln dust to reduce the pollution, several industrial applications have been used CKD to minimize its impact on environment [2][3][4][5][6]. Combining CKD with polymer matrix is another solution to minimize the pollution of CKD, the addition of CKD as filler in polymer composites provide some improvement in the polymer properties as well as reducing the cost of production [7,8].…”
