TECHNICAL FIELD. This invention relates generally to electrical systems for measuring the moisture content of a particulate material, and more particularly relates to the measurement of the moisture content in a flowing, fine aggregate, such as the sand used for mixing portland cement concrete, by means of an electronic apparatus which includes a tuned or resonant circuit.

Better Understand Why the Combination of Moisture and

Jul 27,  · In addition, these concrete mixes can be less permeable which, in turn, slows the release of moisture from the concrete. The increased use of lightweight structural concrete, with its pre-wetted aggregates, adds additional moisture to the mix. Increased moisture in the mix exacerbates the problem of trapped moisture beneath the roof membrane.

Concrete Mix Design - The Best Concrete Mix - The Concrete

Sep 17,  · Using the ACI 211.1 method, here is an abbreviated run-through on how to design a mix: Choose the target slump. Choose the maximum aggregate size—remember that the larger the better for reducing shrinkage and curling. Estimate the water and air content using ACI 211.1 Table 6.3.3. Select the water-cement ratio.

Moisture Measurement – an Essential for Automating

Jul 06,  · Measuring the moisture of fresh concrete in a mixer allows the concrete producer to have full control over the final moisture content before the mix is discharged. Measuring the moisture whilst mixing ensures that variations such as unmeasured aggregates, or environmental influences (rain or evaporation from heat) during transport from the hopper to the mixer, are eliminated.

Step by Step: How to Get a Concrete Slab Ready for Wood

Step 1: First, test the moisture content of the slab to make sure it's ready for wood flooring installation. Never install over a slab that's less than 30 days old. To test,there are several options, including moisture meters, poly film tests and phenolphthalein tests. If any indicate moisture, use a calcium chloride test.
