Abstract

The invention discloses an energy-saving concrete and a preparation method thereof. The energy-saving concrete is composed of the following substances in parts by mass: 80-120 parts of silicate cement, 100-120 parts of broken stone, 12-15 parts of iron powder, 16-20 parts of sodium sulfite powder, 30-60 parts of fly ash, 4-8 parts of industrial waste residue, 6-12 parts of glass fiber, 8-12 parts of coupling agent, 14-20 parts of sodium silicate, 4-10 parts of sodium sulfide, 6-8 parts of activated carbon, 70-160 parts of gravel, 1-3 parts of foaming agent and the balance of water. For the concrete disclosed by the invention, the gas content is 5.5-6% of the volume of the concrete; the concrete has uniform, stable, closed and noncommunicating micro bubbles, thereby preventing capillary channels from being formed in the concrete, and relieving swelling pressure produced by free water freezing; and the freezing resistance of the concrete is effectively enhanced, and the concrete can resist the action of 300 rapid freeze-thaw cycles.

Description

technical field [0001] The invention relates to an energy-saving concrete and a preparation method thereof. Background technique [0002] Concrete is a capillary porous body composed of cement mortar and coarse aggregate. In order to obtain the necessary workability when mixing concrete, the mixing water added should always be more than the hydration water of cement. This part of excess water stays in the concrete in the form of free water to form connected pores and occupies a certain volume. For construction projects in the cold regions of northern my country, concrete in water conservancy projects. [0003] 1) When the concrete is in a water-saturated state: when the water is cold and freezes, the volume will expand. When the pressure generated by the expansion is greater than the tensile strength of the concrete, the internal structure of the concrete will be destroyed. Under repeated freeze-thaw cycles, concrete spalling and strength reduction will be caused. [000...
