QUALITY CONTROL TESTS: Trojan Masonry Sealer has passed nine independently performed quality tests per the American Society for Testing and Materials (ASTM), Australian Standard (AS) and NCHRP specifications. These tests include:
ASTM 413 - “Water Absorption of Chemical Resistant Concrete/Masonry” .Tested the effectiveness of Trojan Masonry Sealer in resisting water penetration. Trojan was applied in 1994 on one of Coca Cola Company’s major exposed concrete roof-top parking structures.
In 1997, three years after application, Coca Cola hired independent laboratory, H.C. Nutting Company to perform the ASTM 413 test. Test results revealed an “excellent” performance in the waterproofing ability of Trojan as it proved that there was no penetration of water from the core samples of the concrete deck.
ASTM C140 - “Masonry Absorption Test for Light Weight Block”. Trojan Masonry Sealer was applied to light weight block and weighed in its dry state. The block was then placed in water for 2 days. Afterwards it was weighed again while still wet. The 2-day test results are as follows:
ASTM requires that water absorption cannot exceed 1% after 2 days of immersion. The results prove that Trojan Masonry Sealer far surpassed these requirements.
ASTM 123D - “Penetration Test for Nuclear Power Plant, 8000 psi Concrete Pour”. This test was performed by Pittsburgh, Plate and Glass subsidiary, Keeler & Long to determine the penetration of Trojan Masonry Sealer on a Nuclear Plant slab that was 8000 psi pour.
Six months after Trojan was applied, the ASTM-123D test was performed by taking two 2” core samples. After diamond sawing the cores in half, the test revealed that the Trojan penetrated 2 inches. As the normal pore for a concrete slab is 3000 to 4000 psi in density, Trojan can easily penetrate 2 to 4 inches on regular concrete.
Blue Dye Test - “Blue Dye Absorption Test”. Independent laboratory, H.C. Nutting Company conducted a Blue Dye Test for the Department of Public Works of Cincinnati, Ohio at the Garfield Garage parking deck. Trojan was applied to the concrete surface along with several other sealers. Afterwards, two 1” diameter cores approximately 2” long were extracted from each test site of the concrete parking deck. The objective of the test was to determine to what extent the blue dye was absorbed if any. Trojan was top rated as “excellent” at not allowing the blue dye to penetrate the concrete surface.
ASTM 642-82 - “Masonry Absorption Test for Brick”. Independent laboratory, H.C. Nutting Company coated a brick with Trojan Masonry Sealer and then submerged the test brick in water for 48 hours. The objective of the test was to determine water absorption of the brick by establishing its weight when dry before being submerged and again weighing the test brick immediately after its 48 hour water submersion. The results showed no weight increase of the brick after it was taken out of the water, thus proving that Trojan provided total waterproofing of the brick by not allowing water to be absorbed.
ASTM C672 - “Scaling Resistance”. Independent laboratory, H.C. Nutting Company completed the scaling resistance test on treated concrete after applying Trojan Masonry Sealer. Test results showed that there was no scaling after 100 weathering cycles (via mechanical brush) on the concrete that was sealed with Trojan as opposed to severe scaling on untreated samples of the concrete.
AS 1012.21-1999 - "Water Absorption of Hardened Concrete". Determination of water absorption and apparent volume of permeable voids in hardened concrete. Trojan Masonry Sealer passed this standard by not allowing water absorption.
NCHRP 244 – Cube Test – “Accelerated Weathering Test”. Trojan Masonry Sealer surpassed the standard of not exceeding 25% of untreated cube absorbed chloride.
NCHRP 244 – Southern Exposure – “Chloride Ion Penetration Test”. Trojan Masonry Sealer did not allow chloride penetration and thus passed absorbed chloride requirements not to exceed 10% of untreated concrete.
