Age of green roof Concrete strain, stress fields of green roofs and engineering measures cover not only the in situ concrete housing heavier than normal load floor panels intensity, and on the seepage, cracking, acid environments have special requirements, and some researchers based on our self-shrinkage deformation of concrete results from the experiments on the formation mechanism of the initial setting of strain were comprehensively described, and combined with the construction of cast concrete roof for the main measures |

The research and engineering solutions to aging strain and stress field of in-situ concrete board with green plants In-situ concrete board with green plants of house roof endures more load then conventional floor and needs more resistance to crack, leakage and acidic environment. By analysis the experimental results of autogenous shrinkage of concrete deformation carried out by us and other researchers, a comprehensive summarization of early stage strain mechanism of concrete was proposed, and a engineering solution to in-site concrete processing of house roof was given. |

The research and engineering solutions to the strain of the board age and stress field of greening roofing with cast-in-situ concrete As compared with mormal roof boards, cast-in-situ concrete boards of planted roof not only were required to endure larger load intensity, but also have higher resistance to split, leakage and acidic environment. According to the experimental results from us and other researchers on autogenous deformation shrinkage of the concrete, a proposed mechanism on the formation of concrete strain at early coagulating stage was comprehensively elucidated and a solution was put froward, based on roofing construction with cast-in-situ concrete . |
