Stable bituminous foams based on diphenyl methane-4,4′ diisocyanate (MDI–isocyanate prepolymers) that combine bituminous membranes and polyurethane foams into one material are promising new materials. They are produced in a two-step process: firstly, a reactive modified bitumen is obtained by mixing a bitumen and a prepolymer, and, secondly, a bituminous foam is formed by a reaction of an excess of...
Foam building materials are used in roofing and water proofing membranes, insulation, pipe covers, vapour barriers, crack suppressant membranes, and as installed flooring protection. In this study, new stable bituminous foams have been developed, in a two-step method, using a reactive polymer, synthesized from the reaction of 4,4′-diphenylmethane diisocyanate with a low molecular weight polypropylene...
This work is part of a comprehensive study on the design of synthetic binders. The overall objective of the whole research was to study the influence that the nature of each binder constituent, its mechanical and thermodynamic properties, binder composition and processing conditions exert on the microstructure and the rheological properties of the final product. Particularly, this work presents and...
