Photosensitive controllable rapid-hardening concrete pouring material and construction method thereof

Abstract

The invention discloses a photosensitive controllable rapid hardening concrete pouring material and a construction method. The pouring material comprises shadowless glue, transparent stone or broken glass aggregate, sand and glass fibers, wherein the transparent stone or broken glass aggregate, the sand and the glass fibers are uniformly stirred and then mixed with the shadowless glue, and full stirring is conducted to obtain the pouring material. According to the method, sunlight irradiation is avoided in the stirring process, and an LED lamp is adopted for illumination; then the pouring material is injected into a mold for molding treatment, a gravity self-leveling mode is adopted for horizontal pouring, and a transparent organic glass mold without an ultraviolet filtering effect is adopted for side pouring; an ultraviolet lamp is adopted for irradiation, ultraviolet rays penetrate into the pouring material through the transparent aggregate and the glass fibers, and the shadowless glue is cured and formed under irradiation of the ultraviolet rays; and the mold is dismounted and directly irradiated by sunlight, so the strength of the pouring material after curing is improved. Thepouring material and the construction method can be used for rapid construction and emergency repair of a concrete structure, and have the characteristics of short curing time, high strength after curing, good durability and the like.

Description

Technical field [0001] The invention relates to the technical field of material engineering, in particular to a photosensitive, controllable and fast hardening concrete pouring material and a construction method. Background technique [0002] Usually the castable is a cementitious material cementing the aggregate into a whole engineering composite material. Among them, concrete is the most commonly used castable in construction engineering. It uses cement as the cementing material, sand and stone as the aggregate, and water ( It can contain admixtures and admixtures) according to a certain proportion and mixed to obtain cement concrete, also called ordinary concrete, which is widely used in construction projects. Concrete has the characteristics of abundant raw materials, low price, and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and wide range of strength grades. T...

AI Technical Summary

Problems solved by technology

[0003] Traditional concrete uses cement as the cementitious material, combining fine aggregate sand, coarse aggregate stones, water and other materials together, and the hydration of cement has a certain time limit, although early strength agents can be added to make the concrete more durable. Fast hardening, but it is impossible to control when and how fast it hardens. If the hardening speed is too fast, the concrete will not be able to form the desired shape. If it is too slow, it will not meet the needs of construction.

Moreover, concrete with stones as coarse aggregates, with the development of the ecological environment, has imposed strict restrictions on quarrying in various regions, making the price of stones as coarse aggregates higher and higher, and the cost of concrete is also higher and higher.

[0004] In practical applications, after some concrete bridges are partially damaged, if concrete pouring materials are used to repair them, multiple procedures such as maintenance are required, and the cycle is long, and the repair process needs to interrupt traffic, which greatly affects the normal traffic order.
