The invention discloses road concrete prepared from waterworks
sludge powder and
coral fine aggregate. The road concrete comprises the following components in parts by weight: 370-430 parts of
cement,36-43 parts of waterworks
sludge powder, 570-590 parts of
river sand, 36-46 parts of
coral fine aggregate, 1120-1170 parts of broken stone, 4-16 parts of quicklime
powder, 1-4 parts of
gypsum powder,166-183 parts of water and 5-9 parts of water
reducing agent, wherein the water-binder ratio is 0.35-0.45. According to the invention, waterworks
sludge powder is used as a mineral admixture to replace part of
cement, and quicklime powder and
gypsum powder are doped to further stimulate and improve the activity of the waterworks sludge powder; and
coral fine aggregate is used for replacing part of
river sand, aggregate grain composition and the 'micro-pump' effect of the coral aggregate are further improved, the local water-binder ratio of the aggregate surface can be adjusted, and the performance of concrete for roads is improved. The concrete for the road is prepared from the perspective of
optimal design of cementing materials and aggregates, so that the performance of the concrete isimproved, the high-added-value green application of sludge powder and coral fine aggregates of waterworks is facilitated, and the comprehensive benefit is high.
