Gypsum is also used in glass manufacturing, for high-strength floor underlays, as a patching material for road and surface repairs and for thermoplastics, thermosets and coatings, as well as for other construction industries (Ghrefa and Howari, 2011). ...
A thin film is formed by the non-re-emulsifiable, and it has excellent water resistance, aging properties, and ultraviolet stability. This latex is commonly used as a bonding agent since it works well with cement. At the same time, emulsifiable polyvinyl acetate latex creates a film that ...
Model the relationship between the performance and chemical composition of patching materials. • Evaluate the feasibility of more polymers as concrete modifiers from the performance perspective. • Investigate the performance exertion of patching material under different degrees of aging of concrete bridg...
The comprehensive evaluation of concrete pavement condition, including the modulus value and internal distress recognition, has the capability to assist in determining the design of overlay asphalt thickness and material. Keywords: pavement engineering; pavement modulus; SASW method; concrete pavement; non...
Large cracks or holes greater than ¼”, spalling (horizontal peeling or chipping of the surface), and discoloration can be covered with resurfacing or a concrete overlay (a thin layer of cement-based material applied directly over the existing concrete). ...

Just before you're ready to install the concrete patching compound, you simply paint a thin coat of the cement paint onto the clean, solid, damp old concrete. Immediately cover the cement paint with the patching compound. Never allow the cement paint to dry. It can dry rapidly if you're...
Possible causes of potholes include asphalt that was too thin, base failure under heavy loads, or poor drainage that weakens the subgrade and base. Poor quality (segregation in the asphalt, poor compaction, or asphalt that was burnt or did not have enough oil mixed into it) may be a contri...
As a high-quality building material exhibiting excellent toughness and durability, ultrahigh-performance concrete (UHPC) is increasingly being used in the construction industry and as building reinforcement. During the reinforcement of existing concrete structures with UHPC, their interface is the weakest ...
In some cases, the concrete is too thin or there are not enough reinforcing materials to support it; in other cases it may be due to improper curing procedures which can happen with new construction projects where the building process is rushed. If your sidewalk has cracks that keep growing ...
