An admixture for making water penetration resistant cement and concrete mixes, comprising:
- (a) a hydrocarbon-based water repellent (HCWR) and (b) a silane-siloxane composition (SS).
A concrete masonry unit (CMU) made of a concrete or cement composition, comprising, (a) a hydrocarbon-based water repellent (HCWR) and (b) a silane-siloxane (SS) composition.
A concrete or cement composition, comprising:
- (a) a hydrocarbon-based water repellent and (b) a silane-siloxane composition.
A cured concrete or cement composition, comprising:
- (a) a hydrocarbon-based water repellent (HCWR) and (b) a silane-siloxane (SS) composition.
A method of making an admixture for concrete mixes, comprising, combining (a) a hydrocarbon-based water repellent (HCWR) and (b) a silane-siloxane (SS) composition.
A method for making a concrete masonry unit (CMU) comprising providing a concrete or cement composition comprised of:
- 4-25% (s/s total dry weight) hydratable cement binder;
- 74-95% (s/s total dry weight) relatively fine aggregate which is an aggregate blend or particle batch containing aggregates as fine or finer than Size Number 8 coarse aggregates as defined in ASTM C 33-07;
- 0.08 to 1.23% (s/s hydratable cement binder) HCWR, and
- 0.02 to 0.30% (s/s hydratable cement binder) SS.
