Abstract

The invention discloses an impact-erosion resistant marine concrete dual-ash gelling powder and a preparation method and device thereof, and belongs to the field of gelling materials. The dual-ash gelling powder comprises following raw materials in parts by weight: 30 to 40 parts of cement, 15 to 25 parts of furnace steel ash, 12 to 20 parts of slag, 15 to 18 parts of silica fume, 2 to 5 parts ofexpanded graphite, 2 to 5 parts of ceramic micro powder, and 5 to 12 parts of rubber powder. The preparation method comprises following steps: preparing raw materials; preparing a basic material; andpreparing the dual-ash gelling powder. The problem that in the prior art, the impact-erosion resistant performance of conventional marine concrete is bad is solved.

Description

technical field [0001] The invention relates to the field of cementitious materials, more specifically, it relates to a scour-resistant marine concrete double-ash cementitious powder and a preparation method and device thereof. Background technique [0002] Marine concrete is also called marine concrete. It is generally believed that the concrete used in structures that are often subjected to splashing by waves belongs to marine concrete. Marine concrete is a high-performance concrete with high workability and high durability. [0003] Marine concrete generally includes cementitious materials, water and aggregates. Under physical and chemical action, the cementitious material can change from slurry to solid stone-like body, and can cement other materials to form a composite solid material with certain mechanical strength. [0004] The cementitious material used in the existing marine concrete is generally composed of cement, mineral powder, and fly ash mixed in a certain ...
