Abstract: Provided are a resin molded component, a method for producing the resin molded component, and a method for producing a welded resin-molded article which ensure appropriate welding at a portion to be welded, without causing insufficient strength. A resin molded component 1 includes a body portion 10 and a rib 11 integrally molded with each other, the rib 11 protruding from the body portion 10 and configured to be infrared welded to a predetermined resin component 2, the resin molded component 1 having a foamed layer 12 formed at least in the body portion 10. A leading end portion of the rib 11 of the resin molded component 1 has a thinned remainder 11b which has been thinned relative to a root portion of the rib. For example, the rib width of the thinned remainder 11b of the rib 11 is smaller than the rib width of the root portion.

Abstract: An object is, in a fly ash-containing cement composition, to disperse fly ash well with addition of a small amount of additive to prevent the deviation of flowability of the cement composition due to the change of unburned carbon content. An additive for a fly ash-containing cement composition includes (A) a nitrogenous polyoxyalkylene derivative represented by formula (1) and (B) a polycarboxylic acid series copolymer having a polyoxyalkylene chain as essential components. R1 represents hydrogen atom or a hydrocarbon group having 1 to 22 carbon atom, R2 represents alkylene group having 1 to 4 carbon atom, A1O represents one or two or more oxyalkylene groups having 2 to 4 carbon atoms, which may be block or random in the case of two or more kinds of oxyalkylene groups, p=0 to 20, q=0 to 20, r=1 to 10, s=0 to 2 and t=0 to 2.

Abstract: In a cement-based extrusion molding composition, deterioration of productivity due to fluctuation of unburned carbon is prevented by ensuring excellent dispersibility of coal ash mainly composed of fly ash, the extrusion pressure in extrusion molding is reduced, and the strength of a molded product in the same curing condition as in single use of silica sand or silica stone powder is developed. The cement-based extrusion molding composition of the invention comprises: 100 parts by weight of a mixture comprising a hydraulic material, a silicious raw material including fly ash as an essential component and a fiber; 0.1 to 1.5 parts by weight of an extrusion aid; 15 to 45 parts by weight of water; 0.01 to 2.0 parts by weight of a nitrogenous polyoxyalkylene derivative represented by formula (1); and 0.01 to 2.
