Carbon fiber sea sand high performance concrete material and preparation method thereof

Abstract

The invention discloses a carbon fiber sea sand high-performance concrete material and a preparation method thereof. The concrete material comprises the following components in parts by weight: 340-450 parts of cement, 160-180 parts of water, 540-780 parts of sea sand, and 1200-1200 parts of gravel. 1400 parts, 20-50 parts of carbon fiber, 2-5 parts of water reducing agent; it is prepared as follows: prepare materials according to the above components, stir the stone and sea sand until they are evenly mixed, then add cement, water and water reducing agent and stir until Mix evenly; add carbon fiber to the evenly mixed material, stir evenly, and you get it. The present invention adopts carbon fiber to replace steel bar, which avoids the saline degradation and deterioration of reinforced concrete, reduces the weight of building components, facilitates installation and construction, and shortens the construction period; at the same time, carbon fiber has vibration damping characteristics and can absorb shock waves, making the present invention The earthquake resistance and bending strength of concrete materials are increased by more than ten times.

Description

technical field [0001] The invention relates to the field of concrete materials, in particular to a carbon fiber sea sand high-performance concrete material and a preparation method thereof. Background technique [0002] With the continuous and rapid development of engineering construction scale, the annual consumption of sand and stone aggregates in the construction field in my country is top ten. According to the statistics of the European Aggregate Association, in 2012, my country accounted for 1 / 3 of the total output of sand and stone aggregates in the world, about as high as 10 billion tons. At present, river sand is still the main source of fine aggregate for construction, but limited by the source and environmental impact, the increase in the exploitable amount of river sand is very limited. Excessive exploitation of river and terrace sand and gravel resources will sharply reduce land resources and destroy the sand and gravel layers that conserve groundwater resources...

AI Technical Summary

Problems solved by technology

However, the inherent defects of traditional reinforced concrete lead to corrosion of steel bars, which greatly shortens the service life of concrete structures.
