Embodiment Construction

[0042]FIGS. 1-5 show a cement board according to embodiments of the invention, and FIG. 6 shows a method for manufacturing the cement board according to still another embodiment of the invention.

[0043]An aspect of the invention provides a cement board 100 as shown in FIGS. 1-5.

[0044]The cement board 100 comprises grain material 10, sand grains 12, fiber material 20, fiber glass 22, cement 30, plastic cement 32, glue 40, and ammonium dichromate 50.

[0045]The grain material 10 includes aluminum silicate grain, finely crushed bones, shells, dry stall pumice, perlite, coral, and coal ash, or their any possible combination. In general, the grain material 10 is mineral material that is light in weight, such that the cement board 100 would be very light compared to other conventional cement or concrete boards.

[0046]The fiber material 20 includes needle-shaped straws, hemp, reeds, bamboo tree, plastic threads, and chaffs, or any possible combination, and the fiber material processed with woo...

Abstract

A cement board includes grain material, sand grains, fiber material, fiber glass, cement, plastic cement, glue, and ammonium dichromate. The grain material includes aluminum silicate grain, bones, shells, dry stall pumice, perlite, coral, and coal ash. The fiber material includes straws, hemp, reeds, bamboo tree, plastic threads, and chaffs processed with wood preservative and fire deterrant. The the grain material, the fiber material, the fiber glass, the cement, the plastic cement, the glue, and the ammonium dichromate are mixed substantially evenly and formed into a board. The ratio of the cement and the plastic cement to the grain material, the sand grains, and the fiber material may be about 10% to 20%. The ratio of the cement to the plastic cement may be about 50% of both in total. The volume ratio of the grain material to the fiber material may be about 50% to 70% of both in total.

Description

BACKGROUND OF THE INVENTION [0001]The present invention relates to a cement board. More particularly, this invention relates to a cement board, which is strong and light.[0002]Usually, cement boards are very heavy for its main component, that is, cement. Such heaviness has been a serious problem in using them.[0003]Accordingly, a need for a cement board has been present for a long time considering the expansive demands in the everyday life. This invention is directed to solve these problems and satisfy the long-felt need.SUMMARY OF THE INVENTION [0004]The present invention contrives to solve the disadvantages of the prior art.[0005]An object of the invention is to provide a cement board.[0006]Another object of the invention is to provide a cement board, which is strong and light.[0007]An aspect of the invention provides a cement board.[0008]The cement board comprises grain material, sand grains, fiber material, fiber glass, cement, plastic cement, glue, and ammonium dichromate.[0009...
