摘要

Compu00d3sito of ash of coal fu00d3ssil and hydrated lime for use as sucedu00c2neo of roller compacted concrete. The invention relates to a composite to substitute concrete compact roll for the application as base layer or subbase of urban roads and highways, as well as to the construction of dams, replacing Portland cement.When applied as a layer of bearing composite of the invention replaces part of the Portland cement.The composite comprises the following: - [fly ash mixtures (CV) + hydrated lime] is the matrix of connection replacing Portland cement; bottom ash (CF) replaces the sand or any household muu00eddo; math rock (RJ) are materials from mining to replace the R OCHA pits of mining.The composite for the application as base layer and subbase presents the following proportion of material, by weight: - (fly ash and hydrated lime) = is the matrix binder that varies between 90 kg / m ^ 3 ^ 160 kg / m ^ 3 - aggregate muu00eddo (bottom ash) = 5 to 20% big aggregate (reject of rock) = 80 to 95%.Alternatively, the composite layer for application as a vase and subbase may comprise one of the following combinations: (fly ash and hydrated lime) + bottom ash + gravel graduated (fly ash + hydrated lime) + sand + reject of rock - (fly ash and hydrated lime) + sand + bri You graduated.The composites for application as bearing layer (coating) presents the following proportion by mass: - (CV + hydrated lime and Portland cement is the matrix binder) = where 10 to 20% of cement is related to the consumption of (grey + hydrated lime)Which corresponds to 200 kg / m ^ 3 ^ 300 kg / m ^ 3 ^ - aggregate muu00eddo (bottom ash and / or sand) = 5 to 20% big aggregate (reject of rock and / or gravel graduated) = 80 to 95%
