Abstract
The method for utilizing the waste includes low-temp. baking, mixing with aluminate clinker, gypsum and active mixture, grinding, and sieving to obtain plasticizing anti-cracking agent. If it is added to cement, plasticizing and expansion of cement take effect, so adapting anti-cracking concrete.
Description
The present invention relates to the utilization of waste in the building material product, belong to building material field.
Naphthalene series high-efficiency water-reducing agent has been widely used for the cement concrete engineering at present.High-concentration naphthalene series high-efficiency water-reducing agent (Na
2SO
4Content is less than 10%) production process in to add usually calcium oxide as alkaline corrective with in and contain acidity in the naphthalenesulfonate formaldehyde condensation compound solution after the sulfonation, produce in a large number with CaSO thus
4Be main throw out (hereinafter to be referred as gypsum by-product), this throw out can cause in the concrete that as being directly used in concrete stability is bad, causes the later strength retraction, so can only be as offal treatment.
The purpose of this invention is to provide a kind of method of handling waste in the high-concentration naphthalene series high-efficiency water-reducing agent production process, make it to become a kind of new useful products.
Content of the present invention is the waste oven drying at low temperature during high-concentration naphthalene series high-efficiency water-reducing agent is produced, obtain gypsum by-product, again with itself and aluminate clinker, gypsum, active addition (shale ashes or flyash), it is levigate to mix the back according to a certain ratio, get final product the plasticizing anticracking agent.This plasticizing anticracking agent can admixture form be used for the preparation and the construction of cement concrete.Its concrete manufacture craft is as follows:
Waste oven drying at low temperature (<100 ℃) in the high-concentration naphthalene series high-efficiency water-reducing agent production is obtained gypsum by-product and aluminate clinker, gypsum, active addition (available shale ashes or flyash) mixing is milled down to 0.08 mm sieve screen over-size less than 10%, promptly gets finished product plasticizing anticracking agent of the present invention.Above-mentioned several proportion of raw materials is: gypsum by-product 50%, gypsum 15-25%, aluminate clinker 10-25%, active addition 25-0%.
The plasticizing anticracking agent that the present invention makes can produce significant plastification (water-reducing rate is up to 15-20%) when mixing in the cement concrete batching and have the compensate for shrinkage function simultaneously.With 10-15%(place of cement rate) mix cement after, cement setting time: initial set 〉=45 minute, final set≤12 hour, 14 days water curing limited expansion rates of sand-cement slurry 0.04-0.06%, can produce 0.6-0.9MPa from stress, 28 days post-shrinkage ratio<0.01% in dry air, can prevent concrete effectively because the cracking that drying shrinkage causes, the cement concrete water-reducing rate reaches 15-20%, compares with the normal concrete of identical workability, and intensity improved 10-15% in 28 days.
Illustrate that embodiment is as follows:
Embodiment one:
Consist of as waste oven dry back gained gypsum by-product: dihydrate gypsum 78%, solubility naphthalene series high-efficiency water-reducing agent solid 22%; Then by following formulated
Gypsum by-product (50%)+luminite cement grog (10%)+dihydrate gypsum ore deposit (15%)+shale ashes (25%) → levigate (0.08mm tails over≤8%) promptly gets I shape anticracking agent
Performance:
Mix 15% I shape anticracking agent, cement water-reducing rate 15%, cement initial set 1 hour 25 minutes, final set 2 hours 15 minutes; Limited expansion rate 0.047% after the sand-cement slurry water curing in 14 days, it is high by 5% to limit shrinking percentage compressive strength rate contrast in 0.007%, 28 day sample in the dry air after 28 days; 28 days strength ratio benchmark of concrete sample high by 10%.
Embodiment two:
Consist of as waste oven dry back gained gypsum by-product: dihydrate gypsum 75%, solubility naphthalene series high-efficiency water-reducing agent solid 25%; Then by following formulated
Gypsum by-product (50%)+luminite cement grog (15%)+dihydrate gypsum ore deposit (25%)+flyash (10%) → levigate (0.08mm tails over≤8%) promptly gets I shape anticracking agent
Performance:
Mix 12% I shape anticracking agent, cement water-reducing rate 17%, cement initial set 1 hour 20 minutes, final set 2 hours 15 minutes; Limited expansion rate 0.057% after the sand-cement slurry water curing in 14 days, it is high by 7.2% to limit shrinking percentage compressive strength rate contrast in 0.005%, 28 day sample in the dry air after 28 days; 28 days strength ratio benchmark of concrete sample high by 11.5%.
Embodiment three:
Consist of as waste oven dry back gained gypsum by-product: dihydrate gypsum 80%, solubility naphthalene series high-efficiency water-reducing agent solid 20%; Then by following formulated
Gypsum by-product (50%)+luminite cement grog (25%)+dihydrate gypsum ore deposit (25%) → levigate (0.08mm tails over≤8%) promptly gets II shape anticracking agent
Performance:
Mix 12% II shape anticracking agent, cement water-reducing rate 20%, cement initial set 1 hour, final set 2 hours 05 minute; Limited expansion rate 0.06% after the sand-cement slurry water curing in 14 days, in the dry air after 28 days 0.008%, 28 day compressive strength rate of residue limited expansion rate contrast sample high by 10.2%; 28 days strength ratio benchmark of concrete sample high by 14.5%.
Wherein I shape anticracking agent can be used for preparing normal concrete or the mortar with higher waterproofing and anti-leakage requirement, as be used for underground or roofing rigid waterproofing concrete, pond or the concrete of the no expansion joint of long distance armoured concrete slab, basic anchoring with concrete preparation and construction, the II type then can be used for requirement and has high application property (but pumping), high volume stability (not splitting), high permeability resistant (reaching more than the S12) and high strength (C50~C70) concrete preparation and construction.
The present invention plastifies anticracking agent and is applicable to the concrete works with higher anticracking, impervious requirement, also be applicable to basic anchoring, grouting, last-cost joint etc. simultaneously, be particularly useful for preparing have high application property, high performance concrete that high volume stability, high permeability resistant and high strength require.
