Concrete Masonry Fire Resistance . Concrete masonry noncoustible constructionis a material possessing excellent fireresistive properties. - The resistance of concrete masonry to fire is well established by extensive testing to be a function of the type of aggregate used in the manufacture of the masonry units and their equivalent thickness.
ASTM''s steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.

High strength concrete is usually specified by engineers in appliions such as high rise buildings. Block fill 7 mm and 10 mm flowable product ranging from 20 to 40 MPa compressive strength at 28 days with options in design slump between 140 mm and 230 mm. Block fill product has been designed to pump through a two inch rubber hose line making it easier when placing into block work walls.
High-Strength Concrete to the steel girder using headed shear studs welded to the uncorroded portions of the web and flange. The repair provides a secondary load path to restore the bearing and shear strength of the girder which was reduced due to corroded section loss. This research project investigates the appliion and performance of
This hose has very high level of flexibility and can be used for wide variety of appliions in the industry. The material used is water absorption resistant and provide the required strength to hose to deal with abrasive material passing through it. SANDHYAFLEX BRAND NAME is a well known name in manufacturing of heavy duty rubber hoses.
standard-strength (class 2-4) concrete pipes, used in conjunction with type H2 or type HS2 bedding support, are suitable (see Figure 1.2 on the following page). The letter H in the terminology indies Haunch support only. HS indies both Haunch and Side support. The numerals after H and HS indie the level of support in the material used.
