The 4 factors, such as specific absorption of aggregate, dosage of fiber, dosage of cement and molding temperature, were assembled properly by orthogonal design method, the effects of the factors on the optimum proportion of asphalt were studied at the same time. 采用正交试验方法分析集料吸水率、纤维用量、水泥掺量及成型温度这4个因素对沥青混合料最佳油石比的影响程度。
On characteristic of different molding methods, margin cement mortars method is put forward to evaluate the workability of porous concrete with non-vibration molding. 根据不同成型方法的特点,提出富余浆量法来评价免振捣多孔混凝土的工作性,并提出工作性评价指标&富余浆量比。
In this paper it took light ceramic globule, cement, perlite and fly ash as the main material, vesicant and the waterproof as the additive, produced a kind of porous material without fibre by the method of common concrete's molding. 本文利用轻质陶粒、水泥、珍珠岩和粉煤灰为主要原料,辅以造孔剂和防水剂,采用一般混凝土的成型方法研制成一种新型无纤维多孔吸音材料。
According to the technical properties and the test methods of the raw materials of the pervious cement concrete, a kind of vibration-type interior molding process was proposed. 针对多孔水泥混凝土路面原材料技术性质和试验方法展开研究,提出上振式室内成型工艺。
Through a series of test, we got the rational ratio of flyash ceramisite. Flyash cement and the light material are confirmed. After batching, mixing, extrusion molding, conservation etc, we got a kind of more flyash content and low bulk density flyash ceramisite. 通过一系列的试验得出以粉煤灰、水泥为主要原料,掺入轻质填料,经配料、搅拌、挤压成型、养护等工艺,能够得到一种吃灰量大、堆积密度低的粉煤灰陶粒。
Hips of IV type loosening, using allograft bone with anatomic reconstruction and bone cement acetabular component molding. IV型松动骨缺损1髋,采用解剖异体植骨,重建髋臼、骨水泥髋臼假体成型。
Cement stabilized gravel, sub-base compaction and vibration using standard molding compared two methods to determine the best dosage of cement, the best water content and maximum dry density control targets. 采用标准击实和振动成型两种方法,对比确定了水泥稳定碎石基层、底基层最佳水泥剂量、最佳含水量和最大干密度等控制指标。
