摘要： PURPOSE:To obtain mortar or concrete having high compression strength with more firmly integrated adhering face to aggregate containing mixing material comprising fine powders of a substance having reactivity with cement hydrate and surfactant in hydration reaction of mixing with cement. CONSTITUTION:In a case of making cement mortar, high early strength cement is mixed with standard sand to be aggregate and mixed with the above- mentioned fine powder (e.g. mixed fine powder of fine powder of bauxite and silica hume). Then, said mixture is further mixed with a mixing material obtained by pre-mixing of surfactants such as AE agent, dispersant and wetting agent. Besides, an amount of said mixing material is preferably about 30wt.% of the high early strength cement. By using of the above-mentioned mixing material, strength of cement paste itself is increased and further adhesion of the cement paste and interface of the aggregate is increased, then integration of aggregate such as gravel or sand, etc., and the cement paste in adhering face is increased. As a result, mortar or concrete having high strength sufficiently exhibiting strength of mortar or concrete is obtained.

摘要： PURPOSE:To obtain a homogeneous strength of a PC plate having a rise by incorporating a form for shaping the outer shape of a concrete product in an annular rotatable support, delivering a partition material, inner molding material into the form, and centrifugally molding it. CONSTITUTION:A cylindrical support 1 is rotatably supported onto a rotary wheel 2. A square rodlike partition material 6 having a thickness corresponding to the thickness of a concrete product is added to a pair of corners at the diagonal position of a square cylindrical forms 5 of square section, and a decorative tile 7 is connected with an adhesive to the inner wall face of the forms 5. A square cylindrical molding material 9 is eventually provided separately by a separator 8 in the thickness of a product in the forms 5. A centrifugal molding machine is started, and concrete is placed in the forms 5 while accelerating the rotation of the support 1. When its strength is achieved and it is removed from the forms, two PC corner panels 10 of L-shaped section are obtained. Thus, the PC plate having rise part can obtain homogeneous strength and satisfactory bonding strength with the finishing material.

摘要： PURPOSE:To obtain the outer wall having excellent water tightness of an underground structure by a method in which a PC plate formwork to be an outer sheathing board is erectly set, a water-proofing paint is uniformly sprayed onto the inner surface of the formwork, and concrete is placed into the formwork. CONSTITUTION:In constructing the outer wall of an underground structure, a PC plate formwork 1 is erectly set and a visco-elastic water-proofing paint is uniformly sprayed onto the inner surface of the formwork 1 to form a water- proof layer 8. A wall reinforcement 9 is assembled inside of the formwork 1, and an inner formwork 10 is assembled. Concrete is then placed into the space between the formworks 1 and 10 and hardened, and the formwork 10 is removed. The outer wall having excellent water tightness can thus be easily built up.

摘要： PROBLEM TO BE SOLVED: To easily form a proper expansion joint irrespective of the thickness of a mortar layer applied on the external wall surface of a concrete building frame. SOLUTION: When a concrete building frame 4 is formed by placing concrete, a groove-shaped recess part 22 cut-out for a part to be additionally placed and for fitting of a joint bar 28 is preformed using a concrete-placing form material 20, and the joint bar 28 is placed in the recess part 22, matching the amount of the joint bar 28 to be projected from the external wall surface of the concrete building frame 4, to the amount of thickness of mortar to be applied. At this time, the amount of the joint bar 28 to be projected is controlled with a projection-controlling member 24 which is laid between the joint bar 28 and the bottom surface 22b of the recess part 22. A fitting member 26 for the joint bar 28 is provided between the projection- controlling member 24 and the joint bar 28. This fitting member 26 is engaged with the both side parts 22a of the recess part 22 by its resilience and is fastened and secured thereto. Grooves 22 for engaging the both side ends 26a of the fitting member 26 are preformed at the both side parts 22a of the recess part 22. The joint bar 28 using a foamed resin material can be also utilized as the back-up material of sealing material.

摘要： PURPOSE:To execute uniform and high quality plastering finish work which is simple to be executed on a construction site and free of cracks and stripping without depending on a skilled plasterer. CONSTITUTION:A fluffy cloth 1 which sets a single surface of a base fabric 1a as a fluffy surface 1b, is used as a base sheet where a plastering finish material, where proper aggregates and a mixing material are added to a binding material, such as plaster or mortar, is applied to the fluffy surface 1b of the fluffy cloth 1 and the oppositeside surface like the state of a sheet. They are solidified so as to produce a main sheet 2, thereby manufacturing a sheet-like plastering finish material 10. A binding material, such as mortar is applied to a concrete surface 20 which is the object of plastering finish work where the base sheet fluffy surface 1b of the sheet-like plastering finish material 10 is applied to the coated surface and bonded.

摘要： PURPOSE:To carry out an easy or automatic removing operation of stain such as cement paste leaked out on the front surface side of stone materials or the like. CONSTITUTION:In a joint layout process, a large number of stone materials 3 are arranged on a form bed 1 for manufacturing a PC (precast concrete) panel under the condition that the front surface side of the stone material is faced downwards. At the same time, between the stone materials 3, temporary joint materials 2 are provided so as to position the whole of them and, in the interval parts on the upper surface side of the temporary joint materials 2, ultrasonic shielding members 4 are fittingly installed. Next, in a concrete placing process, concrete C is placed in a form, in which joint layout is completed, Next, in a demolding process, by demolding after the curing of the concrete C and removing the temporary joint materials 2, a PC panel 5, onto the under side of the concrete of which the stone materials 3 and the ultrasonic shielding member 4 are bonded, is obtained. Further, in a washing process, the stone material arranged surface side of the PC panel 5 is ultrasonically washed by being immersed in the washing solution in an ultrasonically washing tank. Furthermore, in a joint finishing process, after the washed PC panel is dried, finishing joint materials 6 are mounted to the joint parts of the stone materials 3.
