The application relates to the technical field of building materials, and particularly discloses a mortar material capable of degrading formaldehyde as well as a preparation method and application thereof. The mortar material capable of degrading formaldehyde comprises the following raw material components in mass fractions: cement 75-95 parts, quartz sand 100-130 parts, reinforcing agent 10-15 parts, water reducing agent 1-2 parts, dispersant 3-5 parts, stabilizer 0.5-1 part and composite degradation material 30-50 parts; wherein the composite degradation material comprises yttria modified sericite powder, expanded graphite powder loaded with manganese dioxide and tourmaline powder. The mortar material capable of degrading formaldehyde provided by the application has good compressive strength and bending strength and excellent formaldehyde degradation performance, can realize rapid formaldehyde degradation, does not need to rely on a light source, and effectively makes up for the defects of the prior art.

The application provides a C 180 8 cemented sand gravel building material composition and preparation method and application. The composition comprises the following components: cement, fly ash, aggregate A, aggregate B, water, cemented sand gravel special additive, the cement, fly ash, aggregate A, aggregate B and water are weighed according to component allocation ratio, are uniformly mixed and stirred, then the cemented sand gravel special additive is added, is uniformly mixed and stirred, and the product is obtained. The prepared product breaks through the lithology, structure and physical properties of cemented sand gravel aggregate and expands the selection and use range of the cemented sand gravel aggregate, the mixing ratio of different aggregates is proposed, the structure and stress characteristics of the dam are combined, the cemented sand gravel aggregate is successfully applied to each partition part of the dam body, and a precedent of using extremely thin layer and thin layer phyllitic sericite slate as concrete aggregate is created.
