Measurement of Air Content in Concrete

Measurement of Air Content in Concrete

Air content measurement in concrete is critical for ensuring structural integrity and durability of concrete structures, especially in environments prone to severe weather conditions. Accurate air content analysis optimizes concrete's resistance to freeze-thaw cycles and enhances its workability and strength. Several methods are standardized under ASTM guidelines to measure the air content in fresh concrete, each suitable for different concrete types and conditions.
The pressure method,...

Volatilization

Volatilization

Volatilization gravimetry is an analytical technique that measures the mass lost due to the volatilization of the substance. This technique is used to estimate the amount of volatile material in a sample. To perform this method, heat a known amount of the sample to a high temperature in a crucible or other suitable vessel. The volatile substance in the sample evaporates, and the vapor is completely expelled from the crucible either by heating the sample or bubbling a stream of inert gas through...

Background:

Growing concerns about indoor air quality necessitate reducing volatile organic compound (VOC) emissions from products.
Inconsistent emissions testing results among laboratories highlight the need for standardized validation procedures.
A reliable reference material is crucial for calibrating test chambers and ensuring reproducible VOC measurements.

Purpose of the Study:

To develop a diffusion-controlled reference material for calibrating emissions test chambers.
To create a consistent and reliable source for volatile organic compound (VOC) emissions testing.
To improve the reproducibility and comparability of VOC emission measurements across different laboratories.

Main Methods:

A reference material was fabricated by loading toluene into a polymethyl pentene film.
A fundamental emissions model was employed to predict the toluene emissions profile.
Small-chamber emissions tests were conducted to measure VOC profiles and compare them with model predictions.

Main Results:

Measured VOC emissions profiles from the reference material showed good agreement with predictions from the fundamental emissions model.
The developed material demonstrated the feasibility of creating a diffusion-controlled reference source for VOC emissions.
The approach provides a viable method for standardizing VOC emissions testing.

Conclusions:

A novel reference material using a polymer film loaded with a VOC has been successfully created.
This material aids in calibrating emissions test chambers and enhancing the reproducibility of VOC measurements.
The use of such reference materials can foster confidence in emissions testing and create a more equitable testing environment for manufacturers and laboratories.
