| Report on Performance Assessment of Penetron Waterproofing Admixture | ||
| Results: The compressive strength of concrete cubes made and tested at 28 days averaged 47.50 N/mm2 . The 7 days strength averaged at 44.0 N/mm2. In some cases, there were little gain in strength from 7 to 28 days and in others, the gain was as much as 14%. The average 7 and 28 days compressive strength of the control concrete was 41.5 and 46.0 N/mm2 respectively. The figures show that the admixture did not have any adverse effect on the strength of the concrete. | ||

| An Investigation of Plastic and Other Early Age Properties of a Concrete Containing Penetron Admix | ||
| Results: The compressive strength of the Mix-PX at age 3 days was 1.37 times that of the control mix Mix-CT. At the age of 7 days the compressive strength of Mix-PX was 1.30 times that of the control. The addition of Penetron Admix into concrete increased the early concrete strength significantly. | ||

| Properties of Type GP Cement Concrete Modified with Penetron Admix | ||
| Compressive Strength at 3,7,28 and 91 days (AS 1012.9) Results: Cylinder specimens were cast from both Mix-P and Mix-C concrete batches. The specimens were initially cured in moulds and covered with wet Hessian in temperature-controlled room at 23º C. They were removed from the moulds approximately 24 hours after casting and then cured in a limewater tank at 23º C. The compressive strength was tested in cylinder specimens according to the AS 1012.9. The compressive strength of the Mix-P was 1.22 to 1.37 times that of the control Mix-C at ages between 3 days to 91 days despite the slump of Mix-P (130 mm) being much higher than that of Mix-C (80 mm). It was apparent that the use of the Penetron Admix in concrete significantly increased the concrete strength. The increase in compressive strength by the Penetron Admix was proportionately greater at the early ages of 3 and 7 days. An important benefit of the rapid early strength gain is to permit striping of formwork earlier and to speed up the construction process. In the comparison of compressive strength of two concretes, it was reported in Section 4.1 that the air content in the fresh concrete Mix-P would be expected to contribute to its higher compressive strength at all the ages form 3 to 91 days. | ||

| Research Report on Performance Improvement of concrete and Mortar treated with Penetron and Penetron Admix Compressive strength, flexural strength and tensile strength of concrete specimens according to China Standard. | ||
| Results: Penetron Admix enhanced the workability and plastic properties of concrete by reducing the water demand. The addition of Penetron Admix increased compressive, flexural and tensile strengths, and significantly reduced chloride permeability when compared to control concrete with similar slump. | ||
