Engineering of composite materials made of epoxy resins modified with recycled fine aggregate

Science and Engineering of Composite Materials, 2021
The paper presents studies performed on polymer-cementitious composite made of epoxy resin coating modified with aggregate and cementitious substrate. Epoxy resin is a perfect material that can be used to protect cementitious materials.

Creating vascular self-healing concrete using direct ink writing [PDF]

One of the most promising approaches to create self-healing concrete is the use of vascular networks – hollow channels within the concrete through which a (liquid) repair or healing agent can be transported to the crack region.

Laboratory assessment and durability performance of vinyl-ester, polyester, and epoxy glass-FRP bars for concrete structures [PDF]

, 2017
In the last decade, noncorrosive glass fiber-reinforced-polymer (GFRP) bars have become more widely accepted as cost-effective alternatives to steel bars in many applications for concrete structures (bridges, parking garages, and water tanks).

The Paleoenvironment of the Ndutu Bed at Olduvai Gorge in the Context of Middle Stone Age Expansion in Eastern Africa: A Multiproxy Approach to Ungulate Analyses From the Victoria Cabrera Site and Dorothy Garrod Site (MIS 5)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The study of the Eastern African archaeological record is essential for understanding the origin and evolution of the Middle Stone Age (MSA). However, Olduvai Gorge, one of the primary regions in human evolution studies, has few sites associated with the MSA.

Studies on Repairing of Concrete Cracks with Epoxy Resin

Journal of the Society of Materials Science, Japan, 1967
Cracks appearing on concrete or mortar of structures would reduce the life of structure and destroy its functions, because they cause permeation or penetration of air and moisture. For example, water permeation and air penetration through such cracks promote a corrosion of steel frames and bars.As a procedure to avoid such unfavorable consequences ...
