e max = void ratio of the soil at its loosest condition e min = void ratio of the soil at its densest condition γ d = current dry unit weight of soil in-situ (γ d) min = dry unit weight of the soil at its loosest condition (γ d) max = dry unit weight of t

If the soils are very micaceous, however, do not use lime, as it does not react well with micaceous soils. Use cement stabilization for micaceous soils. Research shows that 6% cement mixed 9 inches deep is the optimum combination for economics and strengt

A cement grout with a ratio of 1: 1 (type I cement: water) was pressurized to grout the soil under the pile tips through a pipe of 128 mm inner diameter, 8 mm wall thickness, and provided with a nozzle at the tip.

Although concrete typically begins its life at a highly basic pH of about 13, the pH values at exposed surfaces soon fall as reactions occur between carbon dioxide from the atmosphere and alkalis in the concrete— a process known as carbonation. Over time,

Design of Experiments (DOE) is also referred to as Designed Experiments or Experimental Design - all of the terms have the same meaning. Experimental design can be used at the point of greatest leverage to reduce design costs by speeding up the design pro

What is the difference between cement and concrete? Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Concrete is a mixture of aggregates and paste.
