3) test result:
Table 6.M10 motars service behaviour detects result of the test
Table 7.M10 motars physics characteristic detects result of the test
As can be seen from the above table:
(1) to the influence of M10 motar workability
After control group goes out machine, the water-retaining property of mortar is poor, and bleeding is more, and workability is poor, and operating handle is poor.Comparative example
After 1 goes out machine, the poor water retention property of mortar, pliability is general, and elasticity is general, and glutinous poly- property is poor, and bleeding is more, does not isolate, mobility one
As, workability is poor.In test example 1, after adding long-acting motar additive of the invention, compared with control group and comparative example 1
Compared with sophistication and the operating handle of mortar are lifted, not bleeding, and water-retaining property is improved, and mortar workability is improved, and shows the present invention
Additive is preferable with water-retaining property effect to improving the workability of mortar.
(2) influence of M10 motars denseness and delamination degree
Denseness is to evaluate an important indicator of mortar mobility.The machine denseness that goes out of control group is 90mm, is 55mm after 4h,
Loss late reaches 38.9%, and the machine denseness that goes out of comparative example 1 is 90mm, is 50mm after 4h, and loss late reaches 44.4%, in test example
In 1, after adding long-acting motar additive of the invention, the machine denseness that goes out of mortar is 100mm, is 80mm after 4h, under loss late
20% is dropped to, the workability holding capacity of mortar is significantly improved, be more beneficial for meeting site operation requirement.
Water-retaining property refers to the ability that mortar keeps moisture, and water-retaining property is generally detected and evaluated with delamination degree, according to
To the requirement of motar delamination degree in JGJ/T220-2010, the delamination degree of motar is preferably 10-20mm, and delamination degree is too big
Easily isolate, delamination degree is too small, drying shrinkage is also easy to produce after mortar hardening and is cracked.The delamination degree of control group be 25mm, comparative example 1 point
Depth is 28mm, and in test example 1, after adding long-acting motar additive of the invention, the delamination degree of mortar is 11mm, is met
Specification suggestiveness numerical value, can significantly improve the water-retaining property of mortar, meet the requirement of site operation.
(3) to the influence of M10 motar setting times
In test example 1, after adding long-acting motar additive of the invention, setting time is 6.5h, (solidifying with control group
Knot time 5.2h), comparative example 1 (setting time 5.0h) compare, have significant retarding action to the setting time of mortar.
(4) to the influence of M10 motar volume growth rates
The volume growth rate of the motar of identical proportioning reaches 15.2%, 1m3Motar can save 13.5% original
Material.
(5) to the influence of performance after M10 motar starch
In test example 1, after adding long-acting motar additive of the invention, 28d compression strength is 23.5MPa, and right
Compared according to group (28d compression strength is 16.2MPa), comparative example 1 (28d compression strength is 17.4MPa), to the pressure resistance of mortar
Degree is obviously improved;Meanwhile, mortar 28d rupture strengths are compared and are obviously improved with adhesive tensile resistance strength ratios comparison group, comparative example 1, thing
Reason mechanical property advantage is notable.
