一种用于建筑节能调温的相变保温粉及其制备方法,涉及建筑节能保温材料领域,其特征在于相变材料微细颗粒表面裹覆纳米水硬性凝胶形成的粉状相变保温粉。通过纳米水硬性凝胶形成的外壳,使相变材料在相对独立的空间进行固‑液相转变循环,不会析出、渗漏,特别是为了提高节能调温性能,可以大量添加,不会对建筑材料的强度造成影响。由于相变材料的外壳为水硬性凝胶,因此在建筑材料中的适应性较强,与混凝土、砂浆、腻子、涂料具有极好的相容性和拌合性。进一步,在水硬性凝胶中掺入了导热剂,提高了调温敏感度,使相变材料能够及时吸热或者放热,不但节能,而且始终将建筑物内调整在合适的温度。生产工艺易控,成本低,为相变材料应用于建筑节能调温领域提供了技术支持。 |

Cement-SCM blends employ particle packing principles to increase particle packing density and reduce interstitial spacing between the cement and SCM particles. Particle packing reduces the amount of water required to obtain a cement paste having a desired flow, lowers the water-cementitious material ratio (w/cm), and increases early and long-term strengths. This may be accomplished by providing a hydraulic cement fraction having a narrow PSD and at least one SCM fraction having a mean particle size that differs from the mean particle size of the narrow PSD cement by a multiple of 3.0 or more to yield a cement-SCM blend having a particle packing density of at least 57.0%. |
