The invention discloses super-light
foam concrete. The super-light
foam concrete is characterized by comprising the following materials in parts by
mass: 60-80 parts of ordinary
Portland cement, 10-20 parts of rapid hardening sulphoaluminate
cement, 2-5 parts of
silica fume, 8-15 parts of ultra-fine
fly ash, 0.5-1.0 part of a polycarboxylate
superplasticizer, 1-2 parts of redispersible
powder, 0.05-0.2 part of hydroxypropyl
methyl cellulose ether, 0.1-0.4 part of
polypropylene fibers, 0.02-0.05 part of a superfine MnO2 catalyst, 4-6 parts of
hydrogen peroxide and 50-60 parts of water, wherein a sustained-release
gelatin capsule is filled with the superfine MnO2 catalyst and has the collapse
time limit of 5-10 min. The invention also discloses a preparation method of the super-light
foam concrete. The preparation method is characterized by comprising the steps of weighing, mixing, stirring and pouring. The super-light foam concrete has the advantages of high percentage of close area, low water absorption, high
compressive strength and low heat conduction coefficient. The preparation method of the super-light concrete has the advantages that the
hydrogen peroxide decomposition efficiency can be improved, and the
hydrogen peroxide decomposition speed can be effectively controlled.
