The invention discloses an electric heating concrete plate for heating. The electric heating concrete plate is prepared from the following raw materials in parts by weight: 100 parts of cement, 100-300 parts of heat-conducting aggregate, 0-150 parts of common aggregate, 5-15 parts of a conductive material, 25-55 parts of water, 0-4 parts of a defoaming agent, 0.5-1 part of a water reducing agent and 0.5-1 part of an early strength agent, wherein the early strength agent is at least one selected from calcium acetate and calcium formate. The heat-conducting aggregate is added into the electric heating concrete plate, so the heat-conducting property of the electric heating concrete plate is improved, and the condition of uneven heating of the plate can be improved; and calcium acetate and calcium formate are used as the early strength agent, so the early strength of the poured electric heating plate can be improved, and the resistivity of the plate can be reduced to a certain extent, thereby reducing the consumption of the conductive material and lowering production cost.
本发明公开了一种用于采暖的电热混凝土板材，由以下重量份的原料制备而成：水泥100份；导热骨料100‑300份；普通骨料‑150份；导电材料5‑15份；水25‑55份；消泡剂0‑4份；减水剂0.5‑1份；早强剂0.5‑1份；其中，所述早强剂为乙酸钙或甲酸钙中的至少一种。电热混凝土板材中添加导热骨料，提高其导热性能，并且能够改善板材受热不均的情况；乙酸钙和甲酸钙作为一种早强剂，不仅可以提高浇筑的电热板材的早期强度，并且可以一定程度降低板材的电阻率，从而降低导电材料的用量，降低生产成本。
