1.0 INTRODUCTION

At the request of Cellular Concrete Solutions, RADCO conducted the tests outlined below onMearlcrete cellular concrete per the ICC-ES Acceptance Criteria for Cellular Concrete, (AC272)Effective November 1, 2004.

2.0 MATERIAL DESCRIPTION & FEATURES

Mearlcrete is a lightweight cellular concrete made by mixing Mearlcrete foam with a portlandcement slurry and is deposited by means of a mixer and pressure hose.

The cement, aggregate and water are batched conventionalIy, and the foaming agent is added tothe batch at the jobsite by passing air and foam through a specially designed valve into the mixingchamber. The Mearlcrete foam liquid concentrate is converted to a stable foam using a Mearl foamgenerator or equal. A minimum temperature of 40°F (44°C) is required during placement. TheMearlcrete must cure 24 hours minimum prior to any foot traffic. Factory-sealed containers storedat room temperature have a maximum shelf life of 2 years.

All samples were submitted to RADCO in a test ready condition. Cellular Concrete Solutionsindicated to RADCO that all samples were prepared and conditioned in accordance with theapplicable ASTM standards. See the Cellular Concrete Solutions Sampling Affidavit in theappendix.

4.0 TEST SETUP & RESULTS

4.1 Water Absorption Test, ASTM C796-04

Testing was conducted in accordance with ASTM C796-04, Standard Test Method for FoamingAgents for Use in Producing Cellular Concrete Using Preformed Foam.

Before water immersion, the dimensions of each sample were taken as described in the TestSpecimen Section of ASTM C495. The Water Absorption Test proceeded as follows. Three (3) 6"x 12" (152.4 mm x 304.8 mm) concrete cylinders were immersed in water. Immersion was suchthat the water level in the container was 6" above the top of the samples for the duration of thetest. The cylinders were left to soak for 24 hours before removal. Each sample was then removedindividually and the excess water was allowed to run off for approximately 30 seconds. Eachsample was then weighed and the wet weight was recorded. In addition, the percent weight gainwas calculated based on the initial weight of each sample taken before the test.

Conclusion

In accordance with Table 1 of ASTM C869-91, the maximum water absorption is 25%. Theaverage value of 7% meets the requirements specified in ASTM C869.

4.2 Oven-Dry Density Test, ASTM C495-07

Testing was conducted in accordance with ASTM C495-07, Standard Test Method forCompressive Strength of Lightweight Insulating Concrete.

Page 3 of 7

The Oven-Dry Density Test proceeded as follows. Three (3) 6" x 12" (152.4 mm x 304.8 mm)concrete cylinders were placed in an oven set at 230 ± 18ºF (110 ± 10ºC) and weighed at 24 hourintervals until the loss in weight between successive readings did not exceed 1%. Once equilibriumwas reached, the weight was recorded and the dimensions of each sample were taken asdescribed in the Test Specimen Section of ASTM C495.

Conclusion

The average oven dry density is 30.5 lb/ft3. In accordance with Table 1 of ASTM C869-91, Type Icement is required to fall within 30.4 ± 2.5 lb/ft3. The average value of 30.5 lb/ft3 meets therequirements specified in ASTM C869.

4.3 Compressive Strength Test, ASTM C495-07

Testing was performed in accordance with ASTM D495-07, Standard Test Method forCompressive Strength of Lightweight Insulating Concrete.

All compression strength tests were performed at Twining Laboratories, Inc. in accordance withthe above standard. Conditioning for each sample was performed at the Cellular ConcreteSolutions facility in Golden, CO.

Conclusion

The average compressive strength is 270 psi. In accordance with Table 1 of ASTM C869-91, Theminimum compressive strength of cellular concrete is 200 psi. The average value of 270 psi meetsthe requirements specified in ASTM C869.

Please see the appendix for the individual test values.

4.4 Tensile Splitting Strength Test, ASTM C496/C496M-04

The Tensile Splitting Strength Test was conducted in accordance with ASTM C496/C496M,Standard Test Method for Splitting Tensile Strength of Cylindrical Concrete Specimens.

All compression strength tests were performed at Twining Laboratories, Inc. in accordance withthe above standard. Conditioning for each sample was performed at the Cellular ConcreteSolutions facility in Golden, CO.

Conclusion

The average tensile splitting strength is 37 psi. In accordance with Table 1 of ASTM C869-91, Theminimum tensile splitting strength of cellular concrete is 25 psi. The average value of 37 psi meetsthe requirements specified in ASTM C869.

Please see the appendix for the individual test values.
