Abstract

Disclosed are a silicon-aluminum base marine concrete material and a preparing method thereof. The preparing method comprises the steps of weighing mineral admixtures, portland cement clinker and diagenetic agent and conducting mixing and grinding on the mineral admixtures, portland cement clinker and diagenetic agent, wherein weight ratio of the mineral admixtures to the portland cement clinker to the diagenetic agent is (60-95):(0:30):(1-10), and preparing the mixture into a silicon-aluminum base binding material for use; weighing the prepared binding material, aggregate and admixture for use, wherein the weight ratio of the binding material to the aggregate to the admixture is 1:(4-7):(0.01-0.10); mixing the obtained mixture with water and stirring evenly the mixture; casting silicon-aluminum base marine concrete slurry prepared after the mixture is stirred into a mould to be subjected to maintenance, and finally obtaining the silicon-aluminum base marine concrete material. The prepared silicon-aluminum base marine concrete material has high durability and sea water corrosion resistance, and has a long service life and a low cost.

Description

Technical field [0001] The invention relates to the technical field of concrete materials, in particular to a silicon-aluminum-based marine concrete material and a preparation method thereof. Background technique [0002] Traditional ordinary cement concrete materials have played an important role in the national economy, and they will also occupy an important position in the construction of engineering facilities in the new century. The production and preparation of ordinary cement concrete materials consume a large amount of mineral resources and energy such as limestone, coal, and electricity, and emit a large amount of CO. 2 And SO 2 With the advent of the era of ecological civilization, the development of green concrete has become an inevitable choice. [0003] Marine concrete refers to concrete that is used on the seashore, in sea water or in an environment affected by sea breeze, and is disturbed by sea water or sea breeze. With the acceleration of my country's reform and o...
