The quality of the every cubic metre of foam concrete raw material of table 1 is as follows
Above-mentioned preparation embodiment will can cover the numberical range, and 3 groups of preparation example is to directly cover listed range
End value；100mm × 100mm × 100mm foam concrete test blocks, natural curing 28 is prepared using by above-mentioned preparation embodiment
After it, crushing resistance, unit weight, heat conductivility and the water absorption test of concrete are carried out, the data such as table 2 obtained by experiment
It is as follows.
100mm × 100mm × 100mm foam concrete test blocks are prepared using by above-mentioned preparation embodiment, by reality
The data tested such as table 2：
2 different material dosage experimental data of table
As can be seen that foam concrete compression strength made from the utility model preparation embodiment is not low from above table
In the compression strength for the concrete that conventional method makes, and the lighter weight of the foam concrete, while prepare embodiment
Foam concrete obtained has relatively low thermal conductivity factor；And three prepare in experiment, when match ratio is to prepare the ratio in 1
The individual character performance indicator of obtained foam concrete is ideal.
Comparative example 1
Control group and 2 test groups, control group is set to be prepared according to method described in embodiment 1 is prepared respectively
Foam concrete, test group 1-1 and test group 1-2 use existing two kinds of gelling systems, specific component and dosage such as 3 institute of table
Show, remaining component and dosage are identical with preparing embodiment 1, and are prepared using identical preparation method.
The component and dosage for the gelling system that 3 test group of table uses
By concrete for making made from above-mentioned each test group into the test block of 100mm × 100mm × 100mm, natural curing 28d
Afterwards, according to《Standard for test methods of mechanical properties of ordinary concrete》Test determination in GB/T50081-2002 has carried out coagulation
Native compression strength, according to《Standard for test methods of longterm performance and durability of ordinary concrete standard》Examination in GB/T50082-2009
Regulation is tested, has carried out crushing resistance, unit weight, heat conductivility and the water absorption test of concrete, specific result of the test such as 4 institute of table
Show.
The performance test results of each set product of 4 comparative example 1 of table
By analysis of experimental results, after adding in float stone, float stone, CHARACTERISTICS OF TAILINGS SAND form more beneficial stress with cement and combine shape
Formula under the premise of the compression strength of foam concrete is improved, significantly reduces the thermal conductivity factor of foam concrete
And unit weight；In addition, the comparative test result in float stone addition proves, as 50kg or so, CHARACTERISTICS OF TAILINGS SAND composition is 200kg or so
When, compression strength, thermal conductivity factor and the balanced superiority of water absorption rate three of foam concrete are more prominent, when continuing to increase
When adding or reducing the addition of float stone, the comprehensive performance of prepared foam concrete is decreased obviously, therefore the utility model
In foam concrete prepare match ratio to improve roofing board concrete heat-insulating property, compression strength and water resistance have
Unimaginable effect.
The way of realization that content described in this specification embodiment only conceives utility model is enumerated, this practicality is new
The protection domain of type is not construed as being only limitted to the concrete form that embodiment is stated, the scope of protection of the utility model covers
Those skilled in the art according to the utility model design it is conceivable that equivalent technologies mean.
