Portland cement paper sludge

Portland cement. Paper sludge is currently in use as an alternative fuel. It is classified as Class 2 (liquid alternative fuels) in the Cembureau classification of alternative fuels (5). Paper sludge ash After incinerating paper sludge at approximately 800 °C, the resultant fly ash may contain reactive

Aggregate in Concrete

Recycled concrete will have a higher absorption and lower specific gravity than conventional aggregates. To produce good quality, durable concrete containing a portion of recycled concrete aggregate often requires trial concrete mixes and close monitoring of the properties of the old recycled concrete, with mix adjustments made, as needed.

3. SALINE SOILS AND THEIR MANAGEMENT

The four electrode technique for measuring bulk soil electrical conductivity has been developed (Rhoades, 1976) for use on irrigated soils and on dry land saline seeps in the field. This is a relatively new technique that has great potential for measuring soil salinity in the field without soil sampling and subsequent laboratory analysis.

Roadway preparation & stabilization

Very rigid requirements as to grading and other properties are used in specifying the aggregate to be used in hot-mix asphaltic concrete, sheet asphalt, and portland cement concrete. By contrast the aggregate to be used in a gravel or crushed rock base course is usually controlled by a less exacting specification, allowing the use of locally ...
