本文以廢紙攪碎、浸泡、濾乾、添加膠結料及有色石粉等材料,在經調配、混拌、滾動、造粒成大小不等球狀骨材,澆置彩色紙骨材混凝土,並將彩色紙骨材作配比設計,澆置新拌混凝土再進行超音波、熱傳導、抗壓等試驗,以探討養治時間、彈性模數、熱傳導對強度之影響。
首先對彩色紙骨材之粗細粒料作筒壓強度及吸水率的試驗,擇優作為混凝土之粗細粒料,再以美國墾務局配比法作為混凝土配比設計,澆製成混凝土,並探討養治時間與抗壓強度、彈性模數、熱傳導率等關係,再以迴歸的方式獲得相互間關係曲線,以作為日後工程界設計參考。
由研究結果顯示,在整個混凝土配比中彈性模數、動態彈性模數、動態剪力模數、壓力波速及剪力波速均隨抗壓強度平方根增加而增加。
熱傳導係數介於0.188 W/m*K~0.259 W/m*K 之間,其熱傳導係數僅為常重混凝土的一半,充分顯示紙骨材混凝土為良好綠色建材。
Firstly this article used minced wastepaper and soaked, drained, added
cement materials and colored powder, made into globular aggregate of
different diameters through the processes of water spray , rolling and
granulating, poured color wastepaper aggregate concrete, used the color
wastepaper aggregate for mixture design, and were made of wastepaper
aggregate concrete, then carried out ultrasound, thermal conductivity,
compression etc. tests, it is made to discuss strength the relations among
curing time, elasticity modulus, and thermal conductivity.
First, use the coarse and fine colored wastepaper aggregate carried out
cylinder compressive strength and water absorption test, as a selected good
aggregate used as aggregate of concrete, and used the United States Bureau of
Reclamation mixture method as concrete mixture design, and were made of
color lightweight concrete, then concrete is made to discuss the relations
among curing time, compressive strength, elasticity modulus, and thermal
conductivity ratio. A series of tests are made to obtain the regression curves as
references for engineering and construction.
The research results show that, in all concrete mix ratios, its elasticity
modulus, dynamic elasticity modulus, dynamic shear stress modulus,
compressive stress velocity and shear stress velocity all increase with the
growth of the square root of compressive strength, Thermal conductivity falls
between 0.188 W/m*K and 0.259 W/m*K, Its thermal conductivity is only
half the normal weight concrete, indicating that wastepaper aggregate
concrete is good material.
