Improved living condition of concrete structure placing with wood-based material

混凝土模板胶合板从硬化的混凝土中取出，作为垃圾受潮或焚烧。木材受潮燃烧是一个严重的木材资源损失和二氧化碳排放问题。本项目的重点是在钢筋混凝土结构中储备木材资源，通过不清除混凝土模板中的木质材料来改善结构的绿化条件。(1)对木质材料与混凝土的粘结强度、混凝土硬化过程中水的行为进行了测定。木质材料，如混凝土模板用胶合板和羊毛水泥板，可能对锚效果有效。应力波和超声波的传播速度受混凝土的硬化和水的释放的影响。(2)混凝土硬化后木质材料的存在，对防止混凝土表面结露、提高混凝土的保温性能、控制混凝土内部的湿度有一定的作用。(3)对木质材料的防火性能进行了研究。混凝土浇筑过程中的复合效应可能会延缓木质材料的燃烧速度。

Concrete form plywood Is removed from hardening concrete and Is damped or burned as rubbish. Damping and burning wood has been a sdrious problem as a loss of wood resource and release of carbon-dioxide to air. This project focussed on stocking wood resource In reinforced concrete structure and Improving llvlng condition of the structure by not removing wood-based materials for concrete form.(1) Bonding strength between wood-based materials and concrete, the behavior of water during -concrete hardening was measured. Wood-based materials such as plywood for concrete form and wool cement board might be effective for anchor effect. Velocity of stress wave and ultra-sonlc wave was effected by hardenlng of concrete and release of water. (2) Existence of wood-based materials after concrete hardening has effect for protecting condensation on the surface, Improving Insulation and control of humldlty In the "space.(3) Fire protecting by wood-based materials was investigated. The rate of burning of wood-based material might be delayed by combination effect in concrete placing.
