Physical properties. Insulators are materials that do not conduct electricity plastics (polymers), rubber (elastomers) and ceramics are all insulators. Tables of data usually show the resistivity of materials. The unit of resistivity is the ohm metre. Very low values are conductors and high values are insulators.

Composites are mixtures of two or more bonded materials. Composites are the mixture of multiple materials, which in combination offer superior properties to the materials alone. Structural composites usually refer to the use of fibers which are embedded in a plastic. These composites offer high strength with very little weight.

Physical Properties of Soil. Soil Texture. Soil structure is the arrangement of soil particles into small clumps, called peds or aggregates. Soil particles (sand, silt, clay and even organic matter) bind together to form peds. Depending on the composition and on the conditions in which the peds formed (getting wet and drying out, or

The major natural resource is volcanic material whilst synthetic aggregates are produced by a thermal the thermal treatment of materials with expansive properties. These materials can be divided in three groups—natural materials, such as perlite, vermiculite, clay, shale, and slate; industrial products, such as glass; and industrial by-products, such as fly ash, expanded slag cinder, and bed ash.

Aggregates are granular materials used in construction work. They include sand, gravel, crushed stone, recycled concrete, recycled asphalt, recycled and slags. Recycled aggregates. Recycled aggregates come from reprocessing materials that have previously been used in construction. There are two methods of producing recycled aggregate

This is due to differences in the thermal properties of specific mineral types in the aggregates. Thermal conductivity values obtained using Eq. (2-1) for concretes with densities from 20 lb/ft3 to 100 lb/ft3 correlate better to test data than for concretes outside this density range (Valore 1980).

Nearly all natural aggregates originate from bed rocks. There are three kinds of rocks, namely, igneous, sedimentary and metamorphic. In such, many properties of aggregate depend on the properties of the parent rock itself. Coarse aggregates are classified into two main groups (i) single-size aggregate and (ii) graded aggregate.

Cementitious materials. Supplementary cementitious materials (SCMs) such as fly ash, pozzolans, and slag can be added to the cement. These influence concrete performance, setting time, rate of strength development, porosity, permeability, etc. The key to high-performance concrete is the use of SCMs.
