High-strength thermal insulation concrete for prefabricated member and preparation method of high-strength thermal insulation concrete
The invention relates to the technical field of concrete, and particularly discloses high-strength thermal insulation concrete for a prefabricated part and a preparation method of the high-strength thermal insulation concrete. The high-strength thermal insulation concrete comprises cement, fly ash, slag, ceramsite, a water reducing agent and water, the preparation method of the ceramsite comprises the following steps: mixing the fly ash, the bentonite, the glass powder and the boron carbide, adding water, granulating, drying to obtain a ceramsite raw material, roasting at high temperature, and cooling to normal temperature to obtain the ceramsite. The high-strength thermal-insulation concrete for the prefabricated member, provided by the invention, has a lower heat conductivity coefficient under the condition of ensuring the compressive strength, which is mainly benefited from the ceramsite prepared by the invention, and the ceramsite can effectively reduce the heat conductivity coefficient of the concrete, is high in strength and can effectively ensure the mechanical properties of the concrete.
本发明涉及混凝土技术领域，具体公开了一种用于预制件的高强度保温混凝土及其制备方法。一种用于预制件的高强度保温混凝土，包括水泥、粉煤灰、矿渣、陶粒、减水剂、水；陶粒的制备方法包括先将粉煤灰、膨润土、玻璃粉和碳化硼混合并加水造粒、烘干得到陶粒生料，然后高温焙烧，再冷却至常温，得陶粒。本申请所提供的用于预制件的高强度保温混凝土在保证抗压强度的条件下，具有更低的导热系数，这主要得益于本申请所制备的陶粒，这样的陶粒能有效降低混凝土的导热系数且强度高，能够有效保证混凝土的力学性能。
