design mixed concrete are those for which mix proportions are finalized based on various lab tests on cylinder or cube for its compressive strength. this process is also called as mix design. these tests are conducted to find suitable mix based on locally available material to obtain strength required as per structural design.
echelon split face block standard concrete masonry units (cmus) are integrally colored pre-finished architectural concrete blocks with a beautiful, rough-hewn texture on one or more faces. our split face cmus are molded with two concrete units attached face to face. the units are cured and then mechanically split apart, leaving the split face with
the crushing strength of concrete in most domestic foundations is measured at 15-20 newton’s per square mm. the nominal mix forhouse foundations is called a c15p mix (p = portland cement) and is comprised of 1 cement, 2 sand and 6 coarse gravel. see our mixing concrete project for more information and calculation tables.

principles of good design and good construction in natural hazard prone areas. thoroughly studied, they will also guide on whether to repair or rebuild damaged houses. the descriptions are followed by a code of minimum standards for construction of houses to ensure quality and a sustainable building.
galvanized coating is g60 (0.6 ounce per square foot). g-90 (0.9 ounce per square foot) is recommended for high humidity and corrosive conditions. g-40 (0.4 ounce per square foot) may also be specified for greater economy. heavier galvanized finishes than g-90 can be specified for more severe environmental conditions and exposures.
the international residential code (irc) lays out a series of requirements for pouring a concrete slab on grade. its more than just forms and pouring concrete! the slab has to be at least 3.5″ thick and possibly thicker for expansive or other difficult soils. the area within the foundation walls has to be free of vegetation, top soil or other

concrete joints are used to compensate when concrete expands or shrinks with changes in temperature. concrete joints are normally used to prevent cracks when the concrete shrinks by creating forming, tooling, sawing, and placing joint formers. the pre-planned cracks will provide a better finish concrete product and will be formed in specific locations where those cracks could be monitored.
