Capping Compound from Test Mark
Test Mark Ultra-Strength Capping Compound is a sulfur based compound that ensures even distribution of compressive load forces for concrete strength testing. The compound comes in the form an ultra-thin flake, it melts quickly to a smooth, free flowing liquid for pouring at between 265°F to 290°F (129 to 143°C), with low sulfur odor.For this, concrete samples of three different compressive strengths 17.2, 20.6 and 24.1 MPa were prepared as per ACI mix design methods from each of these aggregates.

Capping Compound. Gypsum capping compound for high strength capping preparation, it can achieve strenght from 5000 9000 psi (350~630 kgf/cm²)after mixing with water for 30 mins. Gypsum is a are done on both concrete masonry unit(CMU) and prisma. Even though capping with gypsum is the time consuming and labour intensive, gypsum is the capping material that represents best. Two important features make gypsum the best capping material: first its high fluidity nature and second sets very fast and gains strength quickly.Effect of Capping Material on Strength of Concrete

Different capping types: (a) Sulfur capping layers, (b) Gypsum capping
Both the sulfur and gypsum capping were difficult to use due to the heavyweight of the masonry prisms. The third capping, however, is relatively new and thus it has not yet been permitted by the ASTM.After simply mixing with water, the gypsum is ready to use immediately and will be fully solidified after approximately 30 minutes and reach the strength over 420 kgf/cm2, Equals to 6000psi. According to the regulations of US ASTM C617 standard, it is allowed to use high strength gypsum in capping cylindrical concrete specimens.Concrete Capping Gypsum, Grade: S-420, Packaging Type:

ASTM C617: Capping Concrete Cylinders With Sulfur Mortar
Significance and Use of ASTM C617. Capping concrete cylinders and grout prisms with sulfur mortar helps to give them a plane, level surface so that force is applied evenly to the entire end surface when the specimen is broken during the ASTM C39 procedure to test compressive strength. Capping will help you to get more accurate Generally, capping plates may be removed within 45 min NOTE 12—High-strength gypsum caps soften and deteriorate on contact with gypsum cement pastes and after 12 h with neat cement with water and cannot be used on freshly mixed concrete or stored in a moist room for more than very brief periods.Capping Cylindrical Test Specimens PDF Concrete Cement
