摘要

Concrete composition comprises, incorporated into the mass of the concrete, an additive of the insecticidal biocide and/or repellent type. Concrete composition comprises incorporated into the mass of the concrete an additive of the insecticidal biocide and/or repellent type selected from (A1) organo(thio)phosphates, (A2) carbamates, (A3) pyrethroids, (A4) nicotinic receptor agonist/antagonist compounds, (A5) GABA antagonists of the fiprol type, (A6) macrocyclic lactone insecticides, (A7) METI I compounds, (A8) METI II and III compounds, (A9) uncoupler compounds, (A10) oxidative phosphorylation inhibitor compounds, (A11) moulting disruptor compounds, (A12) mixed function oxidase inhibitor compounds, (A13) sodium channel blocker compounds, (A14) malononitrile compounds, (A15) repellents and (A16) the compounds amitraz, benclothiaz, bifenazate, cartap, flonicamid, pyridalyl, pymetrozine, sulfur, thiocyclam, flubendiamide, cyenopyrafen, flupyrazofos, cyflumetofen, amidoflumet, 1-acetyl-3-[(pyridin-3-ylmethyl)-amino]-6-(1, 2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-3,4-dihydro-1H-quinazolin-2-one, N-R a-2,2-dihalo-1-R b-cyclo-propanecarboxamide-2-(2,6-dichloro-alpha ,alpha ,alpha -trifluoro-para-tolyl)hydrazone or N-R a-2,2-di(R c)propionamide-2-(2,6-dichloro-alpha ,alpha ,alpha -trifluoro-para-tolyl)hydrazone, and anthranilamide compounds of formula (I). R a, R c = methyl or ethyl; halo = chloro or bromo; R b = H or methyl; A 1 = CH 3, Cl, Br or I; X = CH, C-Cl, C-F or N; Y a = F, Cl or Br; Y b = H, F, Cl or CF 3; B 1 = H, Cl, Br, I or CN; B 2 = Cl, Br, CF 3, OCH 2CF 3, OCF 2H or OCF 2CHFOCF 3; R 6 = H, CH 3 or CH(CH 3) 2. Independent claims are included for: (1) preparing the composition by directly incorporating the additive into the composition or via a constituent of the composition; and (2) protecting a building from harmful arthropods by incorporating the composition into the groundworks and/or at least one wall of the building. [Image] ACTIVITY : Arthropodicide; Insecticide; Arachnicide. A block of concrete, 10 cm high, with passages for the termites, was poured, incorporating Mythic (RTM: chlorfenapyr, 21.5 m/m) in the mixing water. After drying and an infiltration test, the test set-up and performance followed the standard NF X41-541. The barrier effect of the specimen was verified by evaluation of the mortality and penetration of the termites in the clean compartment containing blocks of wood. An evaluation of the blocks of wood following the scoring of EN NF 117 was performed at the end of the test. The test showed that concrete treated with chlorfenapyr (0.05%) had 0% rate of survival of termites, thus prevented termites from attacking a building. MECHANISM OF ACTION : None given.
