A concrete densifier is a chemical applied to a concrete surface in order to fill pores, increasing surface density [clarification needed]. Chemical densifiers are used on polished and non-polished concrete to reduce dusting and wear; on polished concrete surfaces densifiers help concrete take a better polish and make the surface less permeable ...
Polished concrete is a multi-step process where a concrete floor is mechanically ground, honed and polished with bonded abrasives in order to cut a concrete floor's surface. It is then refined with each cut in order to achieve a specified level of appearance. This process also includes the use of a penetrant chemical known as a hardener.
Diamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. It is a crystal that is transparent to opaque and which is generally isotropic (no or very weak birefringence ). Diamond is the hardest naturally occurring material known. Yet, due to important structural brittleness, bulk diamond's toughness is only fair to ...

A diverging diamond interchange ( DDI ), also called a double crossover diamond interchange ( DCD ), [1] [2] is a subset of diamond interchange in which the opposing directions of travel on the non- freeway road cross each other on either side of the interchange so that traffic crossing the freeway on the overpass or underpass is operating on the opposite driving side from that which is ...
Brooke Shields kept her look comfy at the 77th annual Tony Awards. As she graced the red carpet tonight at New York’s Lincoln Center for the Performing Arts, the actor wore a monochromatic ...
A Southwest Airlines Boeing 737-800 passenger plane flew around 500 feet from the ground in Oklahoma City following a missed landing approach, reports say.
Diamond-like carbon ( DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond. DLC is usually applied as coatings to other materials that could benefit from such properties. [1] DLC exists in seven different forms. [2] All seven contain significant amounts of sp 3 hybridized carbon atoms.
