dry weather. During wet weather, the surface may rut a bit, but will quickly dry and harden in sunny and windy weather. However, any great quantity of plastic fines in base gravel will cause problems. If moisture gets under the paved surface, the base will lose its strength and stability and cause rutting or even failure of the pavement.

Estimation of coarse aggregate content- The percent of coarse aggregate to concrete for a given maximum size and fineness modulus is given by Table 4. The value from the table multiplied by the dry-rodded unit weight (the oven-dry (OD) weight of coarse aggregate required per cubic foot of concrete). To convert from OD to saturated surface dry (SSD)


Aggregate Moisture in Concrete - Concrete Construction

May 31, 2013· The absorption of the aggregate indicates the quantity of water which will be absorbed into the pore structure. Most commonly, aggregates will have a moisture content that is either below or above this absorption limit. When batching, it is of critical importance to account for this water. Obviously, if the aggregates are in a surface wet ...


Aggregates for Concrete

crushed aggregate requires slightly higher values. Fine aggregate content is usually 35% to 45% by mass or volume of the total aggregate content. CHARACTERISTICS OF AGGREGATES. The important characteristics of aggregates for concrete are listed in Table 5-2 and most are discussed in the following section: Grading. Grading is the particle-size ...

Water content - Wikipedia

Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, crops, or wood.Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials' porosity at saturation. It can be given on a volumetric or mass ...
