According to the recorded full process fracture curve, the paper calculated and compared the fracture toughness ( kic ), the fracture energy ( gf ) and crack tip opening displacement ( ctod ) of the different strength grade boulder concrete and crushed stone concrete, it is found that the maximal load ( fmax ) and the fracture toughness ( kic ) of boulder concrete and crushed stone concrete increase when the strength of them increases, so does the fracture energy of boulder concrete, but the fracture energy of crushed stone concrete does n ' t obviously increase when it ' s strength increases. the crack tip opening displacement ( ctod ) of all specimens chang less when the strength of concrete increases, so it is concluded that the location of the axle in the ligament of the specimens is relatively stable
根據記錄的全曲線，計算了不同強度等級的卵石混凝土、碎石混凝土的斷裂韌度k _ （ ic ） 、斷裂能g _ f以及裂縫的尖端開口位移ctod ，比較了不同強度等級卵石混凝土及碎石混凝土的斷裂韌度k _ （ ic ） 、斷裂能g _ f以及裂縫的尖端開口位移ctod的關系，發現卵石混凝土、碎石混凝土的荷載峰值fmax 、斷裂韌度k _ （ ic ）隨強度增加而增加，卵石混凝土的斷裂能g _ f隨強度增加而呈增加趨勢，碎石混凝土的斷裂能g _ f隨強度增加變化趨勢平直，增勢不明顯。 -
By using 5000kn pressure - bent testing machine, the specimens of boulder concrete and crushed stone concrete were tested through three - point - bending method and wedge - split tensile method, the scale division of the index dial of pressure - bent testing machine is larger, whereas the predicted test - load is lesser, so the velocity of exerted load is controlled through observing the reading of the multimeter which is connected with the collecting systerm in order to continuously exert test - load
本文使用5000kn壓彎實驗機，對不同強度等級的卵石混凝土和碎石混凝土試件分別進行了三點彎曲試驗和楔入劈拉試驗。試驗過程中，由於實驗機噸位較大，而試驗荷載預計較小，為了能夠有效地控制加載大小和加載速度，採用通過觀察與荷載傳感器相連的萬用表讀數控制加載速度的方法，連續加載。 -
The series equipment versatillty, its performance had achieved the international advanced level, is at present is most effective, the practical reliable crushed stone machine, is suitable specially for the manufacture grinding compound, fireproof the matreial, the cement, the quartz sand, the emery, the stove are cut broken glass the power, the copper ore, the concrete aggregate and so on many kinds of, the crisp materials on the control granulated substance machine energy conserva tion 50 %, is in the present world system qranulated substance equipment
物料由機器上部垂直落入高速旋轉的葉輪內，在高速離心力的作用下，與另一部分以傘狀形式分流在葉輪四周的物料產生高速撞擊與粉碎，物料在互相撞擊后，又會在葉輪和機殼之間以物料形成渦流多次的互相撞擊、摩擦而粉碎，從下部直通排出，形成閉路多次循環，由篩分設備控制達到所要求的成品粒度。 -
Through flat experiment and circle experiment, we research the causes of cracks before hardening of concrete and after. through ingredient experiment, we research the influence of shrinkage from some ingredient ( coal ash, crushed stones and fiber ). in addition, we test some methods of construction to strengthen the anti - crack capacity of r. c. slab in building sites
通過平板試驗和圓環試驗，研究了混凝土在終凝前和終凝后裂縫的各種影響因素；通過摻合料試驗，研究混凝土的一些摻合料（粉煤灰、碎石和纖維）對其收縮變形的影響；另外，還在施工工地進行一些增強樓板抗裂能力的構造措施試驗。 -
Some recycled products are primarily developed for use in public works e. g. asphalt rubber produced from waste tyres for construction of road surface, fill materials containing crushed glass or recycled aggregates for use in drainage layer, road base or non - structural concrete blocks
事實上，某些再造產品主要為公共工程開發，例如由廢輪胎製成的瀝青橡膠可用來鋪設路面；含碎玻璃或再造碎石的填料可用來建造疏水層和路基或製造非結構混凝土磚塊。 -
Firstly, the characteristic performance indexes of recycled coarse aggregate, made from crushed waste concrete, were test in detail. causes and influencing factors of the characteristic performance of recycled coarse aggregate were analyzed by them
首先，詳細測試了廢棄混凝土破碎后的再生骨料特徵性能指標，並據此分析再生骨料特徵性能的起因以及影響因素。 -
According to the demands of sustainable development of construction field, the performance of recycled coarse aggregate concrete, produced with crushed waste concrete, one of the most of waste building materials, was studied in systemly in this paper
