Embodiment 1

[0013] Water purification ecological concrete, the water purification ecological concrete is composed of the following parts by weight: activated oyster shell-chestnut shell powder mixture: 5 parts, aggregate: 80 parts, adhesive: 20 parts, dispersible latex powder: 0.5 part, SM superplasticizer: 0.05 part.

[0014] The aggregate is 10mm cobblestone and ceramsite, and the weight ratio of cobblestone:ceramsite is 2:1.

[0015] The preparation method of the activated oyster shell-chestnut shell powder mixture is that the oyster shell powder and the chestnut shell powder are activated by calcining at 800° C. for 1.5 hours in a high-temperature furnace, and stirring evenly at room temperature. Chestnut shell powder is obtained by pulverizing chestnut shells according to conventional steps.

[0016] The adhesive is Portland cement.

[0017] The preparation method includes the following steps:

[0018] 1) stirring and mixing the activated oyster shell-chestnut shell powder mixture...

Embodiment 2

[0023] Water purification ecological concrete, the water purification ecological concrete is composed of the following parts by weight: activated oyster shell-chestnut shell powder mixture: 6 parts, aggregate: 85 parts, adhesive: 25 parts, dispersible latex powder: 1 part, SM superplasticizer: 0.1 part.

[0024] The aggregate is 20mm cobblestone and ceramsite, and the weight ratio of cobblestone:ceramsite is 2:1.

[0025] The preparation method of the activated oyster shell-chestnut shell powder mixture is: calcining the oyster shell powder and the chestnut shell powder in a high-temperature furnace for 1.5 hours at 1000° C. for activation, and stirring evenly at room temperature. Chestnut shell powder is obtained by pulverizing chestnut shells according to conventional steps.

Abstract

The invention belongs to the field of constructional engineering, and concretely relates to ecological concrete for water purification. The ecological concrete for water purification comprises the following components in parts by weight: 5-6 parts of an activated oyster shell-chestnut shell powder mixture, 80-85 parts of aggregate, 20-25 parts of an adhesive, 0.5-1 part of dispersible latex powder, and 0.05-0.1 parts of a SM high-efficient water reducer. The ecological concrete for water purification changes underground water supplying and purifying effects, at the same time the oyster shell is used, so that resource is recycled as well as environmental destroy and pollution due to oyster shell are reduced.

Description

technical field [0001] The invention belongs to the field of construction engineering, in particular to a water-purifying ecological concrete. Background technique [0002] In the 21st century, human society is facing three unprecedented serious problems, namely, the rapid population growth, the excessive consumption of resources and energy, and the deteriorating environment, which seriously threaten the sustainable development of social economy and the survival of human beings. Taking the path of sustainable development has become the consensus of the world. The main aspects of sustainable development are: more efficient use of energy and materials by conserving and reducing waste while reducing pollution to the environment. [0003] As the most used building material in the 21st century, commercial concrete, the production of commercial concrete consumes a lot of energy and resources. According to statistics, more than 5 billion tons of mineral materials are mined every ...
