| 189 | Admixtures for shrink crack reduction of portland cement-based mortars and concretes | US13116548 | 2011-05-26 | US08784558B2 | 2014-07-22 | Neal Steven Berke; Glenn Eugene Schaefer; Jerry Elliot Rademan; Ronald Wardle; Mark Shand |
| Portland Cement-based concretes and mortars exhibit significant reduction in shrinkage cracking when combined with Magnesium Oxide (MgO), Shrinkage Reduction Admixtures (SRA) and Super Absorbent Polymers (SAP). However, MgO is a solid that reacts with water, SRA is a liquid, and SAP if not added properly could pull water out of the system and thus increase shrinkage. Unique admixture blends used as supplementary cementing materials that do not significantly affect concrete or cement strength properties of Portland cement itself address such issues. Proper ratios of MgO, SRA and/or SAP perform better against crack reduction when compared to commonly used Expansive Cements (EC). | ||||||

| Lightweight cementitious foams of the invention have excellent dynamic and dimensional stability due to use of foaming system comprising polycarboxylate surfactant foam generating agent, foam stabilizer (e.g., PVOH), and shrinkage reducing admixture to inhibit plastic shrinkage and micro-cracking of cement. The foaming system can be used in conventional cement mortars or concretes as well as with exemplary cementitious slurry systems of the invention, which include an expansive agent, a cross-linking agent for the foam stabilizer. Microfibers can be used in the foam, slurry, or both, to prevent micro-cracking. Cementitious foams can be made without use of autoclave or lightweight aggregates to achieve enhanced compressive strength and thermal insulation properties that compare favorably with conventional foams and insulation materials at comparable densities. | ||||||
