TZ - CSA physical and chemical properties
TZ - CSA high performance concrete expansive agent to gray powder.In concrete mixing 6 ~ 8%, can be mixed compensation shrinkage concrete, various performance indexes reach GB23439-2009 standard specified requirements.Mixed TZ - CSA high performance concrete expansive agent of concrete performance is as follows:
1,the crack seepage control performance is good, efficiency is higher.
2, it can reduce the concrete hydration heat, delay the peak of concrete hydration heat and contraction starting time, so as to weaken the concrete temperature contraction, inhibition of concrete structure crack.
3, with the increase of dosage, the expansion rate of concrete increases.
4, adding TZ - late CSA concrete the strength continued to grow, for reinforcement corrosion effect, the sulfate resistance of concrete is higher than ordinary concrete, no pollution to water quality.
5, can be combined with other admixture, but should be concrete adaptability experiment was carried out.
application
1, subway, tunnel, civil air defense engineering, high-rise building basement crack anti-seepage concrete;
2, rigid waterproof roof, seepage control, moistureproof mortar layer, etc.;
3 post-cast strip, buildings and the anchor connecting frame structure joints;
4, the highway pavement, bridge concrete pavement, culverts, etc.;
5, build high strength and high permeability shaft, groove back fill dam concrete;
6, suitable for configuration control temperature cracks of mass concrete and waterproof concrete;
7, applicable to special high performance concrete structure engineering.
Attentions
1, CSA TZ - concrete mixture ratio design for the test.
2, TZ - CSA weighing accuracy, error should be less than 0.5%, together with other material into the blender.
3, mixing time by 30 ~ 60 s than ordinary concrete, the mixing uniformity shall prevail.
4, to the waterproof concrete vibrating close-grained, avoid the appearance of voids, pits and construction joint treatment according to the conventional, but should be wiped with CSA mortar outside sewing a waterproof cover, to prevent the settlement joint and the plastic cracking.
5, avoid direct sunlight, moisture curing of not less than 14 days.When winter construction, should pay attention to moisture, heat preservation.Time may be extended appropriately dismantle in winter, and pay attention to the outer wall of light curing.
6, TZ - CSA concrete expansion joint spacing can be extended to 50 ~ 60 cm, adopt seamless expansion joint design and construction techniques can be cancelled.
7, TZ - CSA concrete can not be used in engineering has long been at above 80 °C;Construction temperature is lower than 5 °C to heat preservation measures.
Packaging and storage
1, use woven bag, and lined with double layers, bags of 50 kg net each, can also according to customer's need to provide other specifications packaging or bulk.
2, transportation and storage should avoid damage and be affected with damp be affected with damp.
3, warranty day is one year.
