There are three commonly used test methods for performing moisture content tests of normal-weight and lightweight aggregates. The Optimum moisture content (OMC) or Optimum Water Content (OWC) is the moisture content at which the soil attains maximum dry density. In almost all applications, the amount of water present in the oil should be monitored. Procedures for determining moisture content of treated material: The Distillation method ("this is Method C - Distillation (secondary) method as de- tailed in ASTM D4442-07) is the appropriate method of determining the moisture content of chemically treated or impregnated material. Signicance and Use 5.1 For many materials, the water content is one of the most signicant index properties used in establishing a correlation between soil behavior and its index properties. TABLE 1 Recommended Heating Times Pine Hardwood Chips (Average Moisture Control 48 % . Specific Gravity and Absorption ( ASTM C 127/C 128, AASHTO T-85/T-84): Specific Gravity evaluates how voids in the aggregate particles are considered. However, there are specialty primers and floor toppings designed specifically for higher MVT rates, up to 9 kg (20 lb)/24 hrs, and up to 99 percent RH. This OMC value is with respect to the specific amount of compaction energy applied to the soil. Moisture content (MC) is a reference to the amount of moisture present in a material. Dry content is the amount of solids which are left after drying given as a percentage of the sample's original (wet) weight. 2.1 ASTM Standards: 2 C 29/C 29M Test Method for Bulk Density (Unit Weight) and Voids in Aggregate C 125 Terminology Relating to Concrete and Concrete .

Moisture content is the amount of moisture in the sample given as a percentage of the sample's original (wet) weight. Shelf life of CURE & SEAL 25 EX in the original tightly closed containers is two years from the date of manufac-ture. Today, most coating manufacturers require concrete substrates to be dry (<5% moisture content) with low vapor transmission (< 3-5lbs per 1000 sq. Water Content (Moisture Content) ASTM D-2216 *Scope* Water content or moisture content is the quantity of water contained in a material. The moisture content of soil (or whatever material being tested) is determined by a source within the gauge emitting neutrons which are scattered or reflected back to a detector within the gauge. Do not allow the accumulation of water, dirt, or other contaminants. Refer to ASTM C1789 Standard Test Method for Calibration of Hand-Held Moisture Meters on Gypsum Panels for the appropriate systematic procedure to calibrate a hand-held moisture meter for use on a specific type of gypsum . The wood scale provides accurate, quantitative readings of moisture over the range of 5% to 30% MC in wood.
