Freeze/thaw resistant cementitious adhesive for composite materials and method for production thereof |
摘要 |
A cementitious paste capable of setting after an interval of time comprises a mixture of a fines component selected from a group consisting of cement and a blend of cement and pozzolonic material, water and a water soluble polymer that is capable of taking up and releasing water when incorporated into the mixture. The polymer comprises a selected percent by weight of the mixture. A non-foamed cementitious composition is also provided to form a substantially homogeneous, pervious rigid mass that comprises a substantially surfactant-free mixture of the fines component, inert aggregate particles, water and a selected percentage by weight of the water-soluble polymer that is capable of adhesion to the aggregate particles. The fines component, the water and the polymer have proportions with respect to one another and together in a proportion with respect to the aggregate particles sufficient in an absence of surfactant to form a substantially uniform adhesive coating on the aggregate particles such that, upon setting, the aggregate particles are bonded to one another at contact areas thereof. A cementitious powder and a method of forming a substantially homogenous, pervious cementitious rigid body are also provided.
