Embodiment
With reference to the accompanying drawings embodiment is further described, the utility model is a kind of building ground on-site concrete that is used for, the equipment of sand-cement slurry rapid curing, this equipment is by electric furnace 5, curing box 4 compositions such as grade, electric furnace 5 places the below of base 3, chassis 1 places the top of base 3, curing box 4 is provided with the top on chassis 1, chassis 3 adopts iron plate to make, thermometer 2 is contained in the fixed orifice on the curing box 4, curing box 4 is provided with pore 6, the size of curing box 4 is 580 * 580 * 200mm, the size on chassis 1 is 640 * 620 * 40mm, the size on chassis 1 is greater than the size of curing box 4, when concrete maintenance is checked, the concrete slurry and the sand-cement slurry that stir are at random made test specimen, the component weight proportion of manufacturing die trial is identical with conventional method, but the Xiamen benchmark sand of proportioning in the cement specimen 7, the porcelain sand that can adopt useless porcelain to be broken into 0.8～2mm replaces, replace Xiamen benchmark sand with useless fine porcelain, meet the regulation of country to cement specimen, regulation points out, " recommend sand water distribution mud test specimen three kind cement 28d to compare with benchmark sand test specimen, error 5% with interior be qualified." pressing that the cement specimen match ratio is supported through three days mark or Rapid Thermal is supported, can test; Through its compressive strength of pressure testing is 10.4mpa, and rupture strength is 2.52mpa, all can reach to join the foster intensity of three days mark of Xiamen benchmark sand.Because porcelain sand intensity is higher, major part has corner angle, and is strong with cement-bonded property, can reduce experimentation cost.Test specimen is contained in 15cm
3In three die trials of body, vibration compacting is floating, covers the iron plate sealing (all coating separant with iron plate in the die trial) of 170 * 170 * 3mm, puts into curing box 4 after preposition half an hour, with the electric furnace heat baking of 600～800W, and plugs 150 ℃ thermometer 2.When temperature is raised to 95 ℃, boiling water is poured into about 5mm height in the chassis 1, steam-cured to keep constant temperature to continue.From being energized to outage 2 hours, at this moment boiling water will consume only, continues to utilize waste heat maintenance (about 40 minutes) taking-up die trial when differing from 30 ℃ with indoor temperature in the curing box to deviate from test specimen 7, cools off and carries out compression test in 20 minutes.By 32.5 cement testings, be 61.3kg/cm than concrete crushing strength with the C20 part
2, surpass 25 ℃ of maintenances of 28 days average temperature and accounted for 26% intensity in three days.
This equipment also can carry out the ruggedness test of cement specimen, match ratio by 32.5 cement, Xiamen benchmark sand, water, replace Xiamen sand with porcelain sand, be made into sand-cement slurry, do experiment with the test specimen of method 16 * 4 * 4cm of curing concrete test specimen, the average 2.6mpa of bending test, the average 10.7mpa of compression test.Above-mentioned equipment in order to realize the quick test of pressure intensity, can in time cooperate the test resistance to compression to the rapid curing test specimen, anti-broken number value at the construction field (site), detects anti-folding test specimen by the method that detects cement specimen; With the portable spring pressure machine (as shown in Figure 2) of this coordinative composition of equipments, the 11mpat and 25 of this machine test 16 * 4 * 4 cement specimens
#The rupture strength of the compressive strength of mixed sand, slurry and machine brick, this machine are that the principle by spring balance is made, and are made of channel-section steel, steel plate, spring and lifting jack, with three days maintenance intensity of compressive stress check C40 concrete test block.Lifting jack is contained in the frame bottom with channel-section steel and steel plate welding, top board is equipped with at the top of lifting jack, test specimen is placed on the top board, spring is fixed on frame top, the pressure of spring designs according to the intensity of check thing, as check the C40 concrete to support test block etc. soon, available 4 groups of springs are pressed 22 tons intensity, the spring allowable stress [α] of pressing silicon steel or silico-manganese steel must not be greater than 90kg/mm2, can improve pressure from the angle analysis big spring cover little spring of the mechanics of materials, reduce materials, in 1000 yuan, the numerical value of surveying with the caliper-gauge scale is scaled kg/cm according to the cost of calculating portable spring pressure machine
2Or mpa.
Can the utility model also can be used for WATER-WASHING METHOD and in time check the technical requirement of the size of the quantity of concrete materials at random, water cement ratio and materials reach the standard of design.
