Abstract

The invention provides a WHDF-N type viscosity modifier applicable to self-compacting concrete. The WHDF-N type viscosity modifier comprises components in percentage by weight as follows: 15%-25% of a crystallization excitation component, 7%-13% of an activity excitation component, 10%-15% of a tricalcium aluminate inhibition component, 6%-14% of a workability regulation component, 2%-6% of an anti-microbe component and 30%-40% of water. Under actions of promoting cement hydration degree, optimizing a hydration product, inhibiting early rapid hydration of tricalcium aluminate, reducing early hydration heat and the like, the WHDF-N type viscosity modifier has the advantages that gel of a system is increased, pores are reduced, an aggregate interface structure and early hydration heat are improved, and the workability and self-compacting performance of a concrete mixture are improved effectively while the crack resistance, impermeability and durability of the concrete are improved remarkably.

Description

technical field

[0001] The invention belongs to the technical field of self-compacting concrete, in particular to a WHDF-N type viscosity modifier. Background technique

[0002] With the large-scale development of western China, the amount of concrete engineering such as roads and bridges, hydraulic dams, railway facilities, and buildings has increased rapidly, and self-compacting concrete will be more widely used. However, so far, most of the research on self-compacting concrete at home and abroad has focused on the preparation of mixtures and other materials. There are few and unsystematic studies on the mechanical properties of self-compacting concrete. The existing research data are insufficient and discrete. . Therefore, it is very necessary to systematically carry out experimental research on the mechanical properties of self-compacting concrete, which will provide a basis for improving the design specifications of concrete structures in the future. Self-compacting c...
