Problems solved by technology

Nevertheless, the engineering plastic test mold still has obvious disadvantages: the stability of the concrete mold is relatively poor when it is vibrated, its rigidity is not as good as that of the steel test mold, it is brittle, easy to damage, and its service life is short.

Abstract

The invention relates to a glass-fiber cement concrete compression strength test mold and a use method. The development of a cement concrete test mold approximately goes through the following severalstages: cast-iron test mold, steel test mold and engineering plastic test mold. The first two kinds of test molds have the advantage of relatively high working strength and the disadvantages of trouble in assembly and disassembly, high price and low cost performance. The glass-fiber cement concrete compression strength test mold comprises a glass-fiber test mold bottom plate (1) and glass-fiber test mold side plates (2), wherein the glass-fiber test mold side plates are arranged above the glass-fiber test mold bottom plate, a demolding hole (3) is formed in the middle position of the glass-fiber test mold bottom plate, and reinforcing rib plates A (4) are arranged at right-angle joints of outer sides of the glass-fiber test mold side plates and adjacent two glass-fiber test mold side plates. The invention is applied to the glass-fiber cement concrete compression strength test mold.

Description

Technical field: [0001] The invention relates to a test mold for compressive strength of glass fiber cement concrete and a use method thereof. Background technique: [0002] The development of cement concrete trial molds has roughly gone through the following stages: cast iron trial molds, steel trial molds, and engineering plastic trial molds. [0003] (1) Cast iron test mold: [0004] Cast iron test molds have high strength and good rigidity, but poor plasticity, high brittleness, easy damage, short service life, difficult to clean test molds after use, heavy monomer weight, high work intensity, troublesome assembly and disassembly, and high price , low cost performance. [0005] (2) Steel test mold: [0006] The steel test mold has all the advantages of the cast iron test mold, and on this basis overcomes most of the shortcomings of the cast iron test mold. It has better plasticity and has a longer life than the cast iron test mold. But it also has insurmountable shor...
