Soil-Cement

Soil-cement can be mixed in place or in a central mixing plant. Central mixing plants can be used where borrow material is involved. Friable granular materials are selected for their low cement requirements and ease of handling and mixing. Normally pugmill-type mixers are used.

Physical and Chemical Properties of Crude Oil and Oil Products

The viscosity of oil is a measure of its resistance to internal flow and an indication of its oiliness in the lubrication of surfaces. There are two types of viscosity: dynamic and kinematics viscosity. Kinematic viscosity (υ) = dynamic viscosity (µ) / density (ρ) The unit of dynamic viscosity is poise (0.1 Pa·s).

Oil has been used for lighting purposes for many thousands of years. In areas where oil is found in shallow reservoirs, seeps of crude oil or gas may naturally develop, and some oil could simply be collected from seepage or tar ponds. Historically, we know the tales of eternal fires where oil and gas seeps ignited and burned.

The mass and energy balances for the cement plant concepts with carbon capture were used furthermore to evaluate the key plant performances. The designs were optimized by performing a heat integration analysis (using pinch technique) for maximization of the overall energy efficiency (Smith, 2005).As an illustrative example, Figure 1 presents the hot and cold composite curves for the calcium ...

Cement Plants: Oil

The only use of oil was in white cement manufacture where a zero-ash fuel was required. However, in the 1950s, the relative price of oil steadily fell. In the late 1950s, a large number of cement plants converted from coal to oil firing. The economic justification for this was marginal, but politics also played a major part in the decision-making.
