9.普通混凝土由水、水泥、砂子、石子组成，必要时可掺入以改善混凝土的某些性能。
10．烧结普通砖的标准尺寸为。
11.低碳钢拉伸过程，经历了弹性阶段、屈服阶段、强化阶段和颈缩阶段四个阶段。
12.砖在砌筑前浇水湿润的目的是13.高碳钢的拉伸性能过程中，无明显
三、简答
1.材料的孔隙率对材料的性质有何影响？
答：材料孔隙率越大，表观密度越小;材料孔隙率越大，密实度越小;对于细微连通的孔隙，孔隙率越大，材料吸水率越大
对于微小开口孔隙，孔隙率越大，材料吸湿性越强;材料孔隙率越大，抗渗性越差
毛细管孔隙易充满水，对材料冰冻破坏影响很大;
一般材料孔隙率越大，导热系数较小，如果孔隙粗大或贯通，导热系数反而增高;材料孔隙率越大，强度越低
2.材料的强度和强度等级有什么区别？
答：强度指在外力作用下抵抗破坏的能力，强度等级是按照材料的强度人为地划分的级别。
3.影响材料吸水率的因素有那些？
答：孔隙率和孔隙特征 4.影响混凝土和易性的因素有哪些？哪些措施可提高混凝土的和易性？
影响因素：水泥浆数量和水灰比；砂率大小；骨料性质（表面状态、级配、粒径大小）；
环境条件（温度、湿度、日照、风速等）；外加剂及掺合料；时间
改善措施：在水灰比不变的前提下，适当增加水泥浆的数量； 通过试验，采用合理砂率；采用级配好的骨料，尽可能选用连
续级配； 调整砂、石粒径，尽可能选用较大颗粒的骨料；选用适当的外加剂或掺合料； 尽可能缩短运输时间。
四、计算
1.含水率为10%的100g湿砂，其中干砂的重量有多少克？
解：Wh=(ms-mg)/mg10%=(100-mg)/mgmg=90.91 g
2．某材料的体积为100mm×100mm×100mm的正方体，其在室内长期放置后测得的质量为2400g，吸水饱和后的质量为2500g，烘干后的质量为2300g，试求该材料的密度、含水率、体积吸水率、质量吸水率、开口孔隙率。（假设无封闭孔隙）
解：密度
材料密室状态体积=自然状态体积-孔隙体积=10×10×10-(2500-2300)÷1=800cm3
ρ=m/V=2300÷800=2.875 g/cm3
含水率
Wh=(ms-mg)/mg×100%=(2400-2300)÷2300×100%=4.35%
体积吸水率
Wv=(mb-mg)/ρw /V0×100% =(2500-2300)÷1÷(10×10×10)=20%
质量吸水率
Wv=(mb-mg)/ mg×100% =(2500-2300)÷2300=8.7%
开口孔隙率
P0=(V0-V)/ V0×100% =(2500-2300)÷1÷(10×10×10)=20%
3.已知混凝土试拌调整后，各组成材料的用量分别为：水泥6kg、水4kg、砂10kg、碎石20kg，并测得混凝土拌合物的体积密度为2400kg/m3。试计算： 每立方米混凝土的各组成材料的用量为多少？
解答：水泥用量为 62400360kg641020
42400240水用量为kg 641020
102400600kg砂用量为641020
2024001200kg石用量为641020
