How do you calculate moisture content in existing concrete floors?

There are several test devised, pertaining to moisture content in concrete! Everything from vapor emissions to relative humidity. By Far the most reliable is ASTM 2170 that measures the relative humidity inside the concrete. Unusual question for a lay person, since most people don't even consider concrete is a giant sponge! Don't fall for ASTM 1869 as a test method --- Very cheap, but not worth much. If someone shows up with a surface moisture meter for testing --- Show him the Door!

To calculate the moisture content in existing concrete floors, you can use a moisture meter designed for concrete. The moisture meter is inserted into the surface of the concrete and provides a reading of the moisture level. It is important to take multiple readings at different locations and depths to get an accurate average moisture content.

What should I do if the moisture content in my home is 33 percent?
Get a dehumidifier.
Can you have minus humidity?
No. This would mean that the moisture content of the air was less than zero.
What is the volume of one ton of topsoil?
Depends on the moisture content and the type of soil.
How do you calculate mass if we are given only volume?
You can't. You need to know content.
What the weight of wood with diameter 4feet and length 16 feet?
This depends on the species of wood and the moisture content of that piece of wood.
Why is it important to minimize the alkali metal content of concrete?
It is important to minimize the alkali metal content of concrete because concrete contains trace amounts of alkali metals like sodium and other minerals and if moisture is present then the sodium reacts with the minerals in the concrete, forming a gel and the gel may absorb water and expand causing cracks in the concrete.
Why you are doing initial moisture content critical moisture content and equilibrium moisture content test?
if we know initial moisture content of the object we can identify how much drying energy required for dry the same moist material. if it is a food material we have to reduce the moisture content upto certain level, otherwise it may be destroyed. if we know the initial moisture content of same food object, we can reduce its moisture content upto 10% of its initial moisture content.
Maximum bulking in sand and in what moisture content?
The maximum bulking of sand is in 13% to 14% moisture content. It's likely to be 13.8% moisture content.
What are the types of Moisture content in coals?

How many water is needed to make a concrete of 1 cubic meter of cement?
varies due to moisture content of aggregate and stiffnes of mix needed (slump)
What instrument is used to measure the amount of moisture?
Moisture meters, under that name, are made for both wood and concrete. There are several designs of these. For measuring the moisture content of the air, an Hygrometer is one type of device. Another device is a Dew Point Meter, quite accurate.
Calculate the percentage moisture content of wood that weighed 120kg as a standing timber and 50kg as a lumber?
the answer is 2.4% you morons what kind of fools are here
How the moisture content of the aggregates obtainable at site affect the water content ratio specified?
Obviously, if the aggregates are in a surface wet condition, meaning the moisture content is greater than the absorption, that surface water increases the water-to-cement ratio and affects strength and durability.
Why is it that materials with moisture content has high k values?
Discuss why materials with moisture content have high k-values
How long would approximately 3 deformed rebar rust and crack through concrete if the bars were forming stakes and come from ground into concrete?
It depends on the moisture content of the soil, the acidity of the soil as well as other factors. "But practically, the answer is forever."
What is the moisture content of fruit powder?
The moisture content in fruit powder should be zero. Any moisture will cause the powder to cling together, and encourage the growth of mould.
What instruments measure air moisture?
A hygrometer measures the moisture content of the air. There are several different types, all of which measure something else which indicates the moisture content.
