Also Abrams' water-cement ratio law. A law which states that the strength of a concrete mix is inversely related to the mass ratio of water to cement. As the water content increases, the strength of the concrete decreases. abrasion The process of scuffing, scratching, wearing down, marring, or rubbing away a substance or substrate. It can be intentionally imposed in a controlled process using ...

Syntactic foams are composite materials synthesized by filling a metal, polymer, [1] cementitious or ceramic matrix with hollow spheres called microballoons [2] or cenospheres or non-hollow spheres (e.g. perlite) as aggregates.
