Abstract

The invention discloses a bamboo fiber lime sand brick. The bamboo fiber lime sand brick comprises the following components in parts by weight: 30-40 parts of fly ash, 7-13 parts of quicklime powder, 50-60 parts of recycled fine aggregate, 3-7 parts of bamboo fiber and 2-5 parts of admixture. The bamboo fiber lime sand brick makes full use of construction wastes, so that resources can be effectively saved, the economy is good and the sustainable development of the construction industry is facilitated. The bamboo fiber is added into mortar, so that the compactness of the lime sand brick can be effectively improved, the strength of the lime sand brick is effectively improved, and the lime sand brick has good waterproof performance.

Description

Technical field: [0001] The invention relates to the technical field of building materials, in particular to a bamboo fiber lime-sand brick. Background technique: [0002] At present, the treatment of most construction wastes is generally only simple landfill treatment or directly stacked in the open air, which has caused serious damage to the ecological environment, and the recycling of construction wastes is becoming more and more urgent. Using construction waste to prepare building materials has become a trend. It can not only save a lot of cultivated land resources, but also enable effective recycling and utilization of construction waste. It can be said to kill two birds with one stone. [0003] With the rapid development of my country's economy and a large number of construction projects, the demand for building bricks is increasing. Since 2008, in order to protect the cultivated land resources, the use of clay bricks has been completely stopped nationwide. For a whil...
