H---- sample fractures face minimum thickness, mm
Span between L---- support sticks, mm.
Retractility measurement method is as follows：After the good 1d of test material preparation, it is intact whether detection gauge head is fixed, if there is pine
It is dynamic, then it can be fixed with waterglass intact and installed again.Test block is put in the water of (20 ± 2) DEG C later, the water surface is higher than water
20mm impregnates 72h.Test block is taken out to and wiped the water of test block surface and gauge head, Centigrade scale or micrometer is used to carry out at once
It measures, a period of time such as quality surveys again.It is put into (20 ± 1) DEG C after having surveyed once, relative humidity (50 ± 5% constant temperature and humidity
In room.It is measured daily until the undulating value in continuous 3d between arbitrary 3d is then put into baking oven and takes out afterwards for 24 hours less than or equal to 0.01mm
Mass metering places into 1h in baking oven and further takes out mass metering, until constant weight.Test specimen air shrinkage value is calculated at this time.Take the calculation of 3 pieces of test specimens
Art average value is corrected as test result to 0.01mm/m.Formula is as follows：
In formula：S --- drying shrinkage value, unit mm/m
L1 --- test specimen initial length, unit mm
L2 --- length after test specimen drying, unit mm
(η1+η2) --- the sum of two gauge head length, unit mm
The Performance result of gained materials for wall see the table below 1.
1 each group materials for wall Performance result of table
It can be obtained by 1 result of upper table, present invention gained materials for wall all has higher failing load, resists in 7d and 28d
