The invention discloses oil-based rock debris
cement paste which comprises the following raw materials in parts by weight: 90-100 parts of
cement, 10-15 parts of oil-based rock debris, 30-40 parts of
metal powder, 1-3 parts of an anti-freezing agent, 1-3 parts of an
antibacterial agent, 1-3 parts of a defoaming agent, 15-35 parts of
gypsum powder and 30-35 parts of water. The preparation method of the oil-based rock debris
cement slurry comprises the following steps: weighing the raw materials, crushing and sieving the raw materials, uniformly mixing the raw materials, calcining and cooling the raw materials, and stirring the raw materials to prepare
slurry. The main component of the oil-based rock debris subjected to
thermal desorption treatment is a siliceous material, so that the cement component is reduced, the cost is reduced, and the waste
utilization rate is high; wherein the
metal powder are slags, so that the compression resistance of the cement is enhanced; due to the anti-freezing agent, the
cement paste is good in use state under the low-temperature condition; moreover, the
antibacterial agent endows the cement with a good
antibacterial effect, wherein the nano
titanium dioxide has a photocatalytic function, can generate hydroxyl radicals with high oxidability in water after absorbing light, and plays a role in sterilization.
