Magnesium cement board and its items have
wide application prospect, however during the time spent creation and
application, magnesium concrete. Magnesium cement board may be volume withdrawal and volume
development noticeable all around. The particular execution relies upon
numerous variables, for example, temperature, moistness and blend proportion of
magnesium concrete itself. Also, the locale is extraordinary, the condition is
unique, so it is hard to utilize an arrangement of logical strategies to
evaluate and control it. At the point when the volume is temperamental,
magnesium concrete items may progress toward becoming drying shrinkage,
extension, break, and twisting distortion et cetera, mischance may be occurred
in a genuine condition.
The volume of material created by
fortification consumption is 2 ~ 4 times to the first steel, and volume
development produces pressure which prompt splitting and peeling of the solid.
The harm of the solid cover can truly decrease the holding energy of the
structure, and defensive layer peeling and burst makes destructive substances
more prone to come into contact with the steel bar, additionally accelerating
the fortification erosion. In the interim, support consumption influences its
cross-sectional region to wind up plainly littler and the bearing limit move
toward becoming lower. The neighborhood consumption of steel bar is more unsafe
than normal erosion, since nearby consumption constantly diminishes the
sectional zone of the rebar, making steel neglects to weight-bearing and
causing a disastrous disappointment of the solid structure.
Lately, a ton of assets have been put
resources into advancement and application parts of Magnesium oxychloride
concrete items at home and abroad some advance has been made and generation
proportion and process has been always moved forward. It has been enhanced item
quality and expanded the assortments based on the first. These items can be
generally isolated into the accompanying a few perspectives as indicated by the
extent of use. It is easy to fabricate magnesium oxychloride concrete items by
including fly powder thirty five percent in the meantime; it can cost
investment funds, and advantages society, economy and condition. The
fundamental reason that enhances water protection is the change of pore
structure of magnesium oxychloride cement item.
There were a few deficiencies about
Magnesium oxychloride cement items, yet the most clear one which made them
farfetched was dampness assimilation halide. Accordingly, magnesium oxychloride
concrete items have been restricted as a divider or roof designing materials.
Aversion and control of dampness assimilation, return halide and the techniques
and measures of the ice can be generally partitioned into three classes:
Control the procedure states of creation; including admixtures; post-preparing
of item.
