Concrete cement is the most widely used building material applicable in road construction. Under real exploitation conditions concrete structures are subjected to different types of local destructions such as cracks which lead to the destruction of the roadway as a whole. In order to ensure the safety, stability and durability of the road coating, technology scheme for using ...

This article summarizes the development and research status of coconut shell fiber, briefly describes the preparation method of coconut shell fiber, and analyzes the performance of the coconut shell fiber cement-based composite material through literature research method and experimental research method, and points out that the material is in stress Application and research value ...

В этой статье описывается разработка круглой самовосстанавливающейся микрокапсулы с материалом ядра в качестве основной стенки капсулы и дополненная физическим методом. Чтобы проверить ее эффективность, микрокапсула была смешана с цементным субстратом для подготовки теста

Additional ingredients in the composition of concrete help to improve its structural and technical parameters. For example, concrete has increased resistance to tensile, abrasion, shock loads, they serve as a rigid skeleton, minimize possible shrinkage by 10 times, protect the structure from deformation during operation, reduce thermal conductivity and creep, reduce the average ...

Microcracks in the cementitious matrix are difficult to detect and repair until they appear on the surface. The binder in the microcapsule can repair the internal microcracks in a short period of time, and shows good repair effect in improving the strength and pore structure of the cementitious matrix, but the repair effect is not good for secondary cracking and surface cracks. ...
