Embodiment 2
[0030] Embodiment 2 is different from Embodiment 1 in that another preference is that the volume ratio of cement:sand:gravel:steel ring is 0.6:1:1:1.6:0.5. The rest are the same as the first embodiment, and the description will not be repeated again.
Embodiment 3
[0031] Embodiment 3, the volume ratio of cement:sand:gravel:steel ring is 0.65:1:1:1.8:0.55. The rest are the same as the first embodiment, and the description will not be repeated again.

Abstract
The invention relates to the technical field of concrete, in particular to steel rim concrete. The steel rim concrete is prepared from water, cement, sand, gravel and steel rim according to volume ratio of 0.6-0.7:1:1:1:1.6-2:0.5-0.6. The steel rim is in a strip rectangular frame shape. The steel rim concrete of the invention has lower cost and can effectively save resources.
Description
Technical field: [0001] The invention relates to the technical field of concrete, in particular to steel ring concrete. Background technique: [0002] Ordinary concrete is a mixture of cement and aggregates (sand and crushed stone). When a certain amount of water is added, the cement hydrates to form a microscopic opaque lattice structure that wraps and binds the aggregate to form an overall structure. The tensile strength of ordinary concrete is low, and any significant stretch-bending action will cause its microscopic lattice structure to crack and separate, resulting in structural damage. Most of the structural components have the requirement of tensile stress inside, so this kind of project generally mainly uses reinforced concrete with steel bars. The tensile strength of steel bars is relatively high, generally above 200MPa. Therefore, steel bars are usually added to ordinary concrete, and the steel bars bear the tensile force, while the concrete bears the compressive...
