TL;DR: In this paper, the authors present a series of studies of brittle fibers containing adhesives or sealants, where and when the matrix cracks, causing the fiber to crack and release chemicals.
TL;DR: In this paper, a taxonomy and construct of research in concrete waterproofing research is established and three classification of additives based on material structure, method of application and additives functions are established.
TL;DR: In this paper, a self-adhesive type multi-layer laminated bituminous roofing membrane suitable for the formation of the roofing or waterproofing layer on roofs, floors and the like is provided.
Abstract: A novel self-adhesive type multi-layer laminated bituminous roofing membrane suitable for the formation of the roofing or waterproofing layer on roofs, floors and the like is provided. It comprises a base sheet of a sheet-like material, one or more bitumen layers coated on all or part of one or both faces of the base sheet, at least one layer of compound bitumen including both bitumen and rubber and/or resin laminated on all or part of the surface of said bitumen-coated layer on the base sheet and at least one release sheet laid over the whole surface of said compound bitumen layer. This roofing membrane is produced by uniting the bitumen-coated base sheet and the compound bitumen-coated release sheet, and can be applied over a substrate in a simple manner, without the step of melting or liquefying bitumen as in the conventional application process.
TL;DR: In this paper, the results of a study conducted to evaluate steel reinforcement corrosion and some physical properties of concrete specimens coated with two polymer-based, a cement-based polymer-modified, and a cementbased waterproofing coatings were reported.
Abstract: This paper reports the results of a study conducted to evaluate steel reinforcement corrosion and some physical properties of concrete specimens coated with two polymer-based, a cement-based polymer-modified, and a cement-based waterproofing coatings The coated and uncoated concrete specimens were subjected to accelerated corrosion to determine the time-to- corrosion initiation The physical properties were also evaluated by subjecting the concrete specimens to wetting/drying cycles and heating/cooling cycles for five months The physical properties evaluated were water absorption, water permeability, chloride permeability, and adhesion The accelerated corrosion test results clearly showed that the specimens coated with the polyurethane elastomer-based waterproofing material performed better than concrete specimens coated with other waterproofing materials This was followed by the specimens coated with cement-based polymer modified, epoxy-based, and cement-based coatings in descending order The two polymer-based coatings showed better performance than the cement-based polymer-modified and cement-based coatings in terms of the evaluated physical properties
TL;DR: In this paper, a nonlinear finite element model is developed to simulate the gasket-in-groove sealant behavior, and the performance of the model is validated with experimental data.
