Embodiment 1
[0044] Step 1: Use a jaw crusher to crush the coral aggregate, sieve the coral aggregate with a particle size of 10mm, and dry the coral aggregate at 105°C for 24 hours; after drying, immerse the coral aggregate in water Soak in a closed container with a glass modulus of 3.5 and a Baume degree of 40% containing sodium water glass, and at the same time use an ultrasonic oscillator to vibrate the coral aggregate to discharge the gas in the coral aggregate; after soaking for 2 hours, seal the coral aggregate Take it out of the container, wipe the surface clean, and put it into a 105°C oven for water glass dehydration. After 6 hours, take out the dehydrated coral aggregate, put it in a saturated calcium chloride solution and soak it for 12 hours, and put it in an oven at 80°C for drying for 6 hours after taking it out. Soak the coral aggregate in the sodium water glass solution for 2 hours again, take it out and dry it, soak it in a saturated calcium chloride solution for 2 hours,...
Embodiment 2
[0048] Step 1: A method for enhancing porous coral aggregates, using a jaw crusher to crush the coral aggregates, sieving the coral aggregates with a particle size of 10mm, and drying the coral aggregates at 105°C for 24 hours; drying Finally, put the coral aggregate in a closed container, use a vacuum pump to draw the air in the container to 0.01 standard atmospheric pressure, and then immerse the coral aggregate in the enhancer A in the airtight container, that is, the water glass with a modulus of 2.5, wave Mido is 35% sodium water glass; after soaking for 8-12 minutes, take the coral aggregate out of the airtight container, wipe the surface clean, and put it in an oven at 80°C for water glass dehydration. After 6 hours, take out the dehydrated coral aggregate, put it into enhancer B, that is, soak it in a saturated calcium chloride solution for 12 hours, take it out and put it in an oven at 80°C for drying. Soak the coral aggregate in the sodium water glass solution for 2 ...
Embodiment 3
[0052] Step 1: Use a jaw crusher to crush the coral aggregate, sieve the coral aggregate with a particle size of 10mm, and dry the coral aggregate at 105°C for 24 hours; after drying, immerse the coral aggregate in a container The modulus of water glass is 3, and the degree of Baume is 45%. Potassium water glass is contained in potassium water glass. At the same time, the ultrasonic oscillator is used to vibrate the coral aggregate to discharge the gas in the coral aggregate; after soaking for 1.5 hours, put the coral aggregate in a closed container Take it out, wipe the surface clean, put it in a 105°C oven for water glass dehydration treatment; take out the dehydrated coral aggregate after 7 hours, put it in enhancer B, that is, soak in saturated calcium chloride solution for 10 hours, take it out and put it in Dry in an oven at 80°C for 5 hours. Soak the coral aggregate in the potassium silicate solution for 2.5 hours again, take it out and dry it, soak it in a saturated ca...
