Problems solved by technology

Studies have found that nearly 20% of the cement in concrete has not been hydrated and is only used as a filling material, which not only causes waste of cementitious materials, but also causes the cement to not fully exert its strength

Embodiment

[0051] 1. Construction site preparation

[0052] Site preparation includes: leveling the site, cleaning the site garbage and floating dust, cleaning the floating soil in the site, so as not to affect the bonding force between the foam concrete and the base layer after pouring, keeping the site to be treated clean, flat, firm and dry; watering the site when the weather is dry Pretreatment, wet the site, sprinkle at least twice to increase the bonding force between the pouring layer and the base, but there should be no obvious water accumulation on the surface of the base, so as to prevent the foam in the foam concrete from breaking due to excessive water absorption at the base; The site is divided into an area of ​​less than 400m by formwork 2 The area of ​​the formwork should be fixed with formwork brackets to prevent the formwork from collapsing due to the lateral pressure of the foam concrete during construction; the height of the formwork should be adjusted according to the...

Abstract

The invention discloses a construction method of an air coating material with an additionally-added synergist in a road. The construction method includes the following steps of (1) construction site preparation, (2) concrete synergist preparation, (3) concrete slurry preparation, (4) foam preparation, (5) foam concrete preparation, (6) foam concrete pouring, and (7) foam concrete curing. By the adoption of the construction method of the air coating material with the additionally-added synergist in the road, the use amount of cement can be reduced, the hydration degree of cement minerals is increased, the number of gels is increased through promotion of hydration of the minerals difficult to hydrate, and the strength of foam concrete is improved. Meanwhile, by the adoption of a constructionprocess of the cast-in-place foam concrete, continuous pouring can be simply, conveniently and efficiently achieved, and the pouring quality of the cast-in-place foam concrete meets the site construction requirements.

Description

technical field [0001] The invention relates to a construction method of an air wrapping material added with a synergist in roads. Background technique [0002] In the western part of China, the terrain is dominated by mountains. The construction of expressways in mountainous areas is limited by terrain, geomorphology, and hydrogeological conditions. It is inevitable to carry out high-fill expansion construction on the original roadbed; at the same time, in order to meet the overall planning requirements of the country , and make better use of excavated earthwork resources, more and more high-fill roadbeds will be used in the reconstruction and expansion of expressways. In high-grade highways in mountainous areas, fill and excavation roadbeds account for 80%, and high fill embankments exceeding 20m are not rare. With the promotion of national policies and the rapid development of traffic construction, the structure of high embankments will be further improved in terms of qu...
