A Study On The Imitate Wood Materials That Can Be Used As Concrete Formwork

Artificial wood made from magnesium sulfate gelled material , bits of wood and bamboo chips, taking place of concrete, is characterized by the properties of hardly burning and deformation, halogenide-resistance,nailableness,being saw, low density, high refractoriness and environmental protection, especially not rusting the metal.A study of proportioning test of woodgrain stuff made of the gluey material,which is made by sulphur,oxygen,magnesium should be done in the condition of ordinary temperature. In order to improve all the properties specified for the gluey material, many kinds of additive agents are added into the woodgrain stuff on the foundation of starting point. Preparation by screening the heighten additive agents is citric acid, trisodium citrate, saccharobiose, then after the optimization experiments of additive agents are conducted, the proportioning of the sulphur,oxygen,magnesium gluey material is determined. In order to increase the strength of gluey material, decrease production costs, reduce fissile, impove water resistance of woodgrain stuff, flyash and mineral waste residue used for packing and stuffing are experimentize. It is reveal that the effect of flyash's is the best stuff in the woodgrain stuff.A mold for the setting of concrete has been use to measure the static bending strength of the woodgrain mold,when we make the test specimen of woodgrain mold and inlay two pieces of bamboo chips or fiberglass meshon on upper and below. Overpass the physical property quota of test research specimen, that the bamboo chip one`s static bending strength is much higher is obtained, and the maximum of strength of 7d is 16.6MPa, reaching 55% in item design of strength value. at the same time the density, water absorption, nail-holding ability are all in accordance with thenational standardsAll in all, woodgrain stuff must be turn into a sustainable development material and new energy saving environmental protection functional construction material, and will have an great effect on construction industry .
