How long does it take to dry soil in a microwave oven?
Inspections of field and laboratory moisture content testing indicated that the typical drying durations for a convection oven and st ove were, 24 hours and 60 minutes, respectively. The objectives of this study were to determine the accuracy and soil drying duration of microwave ovens. This was accomplished by testing soils with and without additives. The soils were tested with a con vection oven (CO), computer controlled microwave oven (CMWO), standard microwave oven (SMWO), and stove. The convection oven was considered to produce the true moisture content and was, therefore, used as a basis for comparison for the results of the othe r devices. Based on appraisals of the results, the standard microwave oven is the most feasible device to use in drying soils .

The soil is stirred and heated until all the moisture is evaporated. Errors in moisture content determination can occur in several ways. First, the amount of heat used to dry the material is determined by the skill and experience of the operator. If the material is overheated, vaporization of the organics in the soil and the asphalt coating on rec ycled pavement blended with the
What oven was used to test soil moisture?

What is the power rating of a microwave oven?
The required power rating of the oven is dependant on its intended use. Ovens with variable power controls and input power ratings of about 700 watts have been found to be adequate for this use. Variable power controls are important and reduce the p otential for overheating of the test specimen [ 4].” Gilbert [3] and Mendoza and Orozco [1] both used typical house -hold microwave ovens in their studies. Neither reported any challenges or failures from using the microwave oven to dry soils. Note 3 of ASTM D4643 -93 states, “The use of a microwave oven for the drying of soils may be considered abusive by the manufacturers and constitute voiding of warranties. Microwave drying of soils containing metallic materials may cause arcing in the oven. Highly o rganic soils and soils containing oils and coal may ignite and burn during microwave drying. Continued operation of the oven after the soil has reached constant weight may also cause damage or premature failure of the microwave oven [4].” Gilbert [3] recommended that a brick be placed in the microwave oven to prevent damage or premature failure of the microwave oven . Since there is water trapped in the brick which can not be dried out, there is no danger in creating a “no water load scenario to damage the microwave oven’s heating element.” Therefore, a standard microwave oven has been proved to be adequate for testing soils by the researchers listed above .
