1. Aggregation: sampling and testing of specific coarse aggregate. Coarse aggregate must be made of gravel or crushed river pebbles, with appropriate gradient direction, excellent material and symmetrical material. Roughly speaking, the index value must comply with relevant specifications, policies and regulations. It is forbidden to manipulate the sand slurry composition and sand slurry composition, immediately detect them, and put the detected defects into the 4-party self feeding concrete mixer.

2.混凝土：混凝土应按照规定抽样。每一批混凝土键入都必须规范的一致性和温度检测。假如您对品质有疑问，禁止进到库房并再次检测别的指标值。严苛严禁应用达标的混凝土。禁止在新项目中立即应用没经加温的高溫混凝土。

2. Concrete: concrete shall be sampled according to regulations. Each batch of concrete must be tested for compliance with the specifications and temperature. If you have questions about quality, do not enter the warehouse and test other index values again. Strictly prohibit the application of qualified concrete. It is forbidden to immediately apply unheated high-temperature concrete in new projects.

3.矿物质化合物：依据相关规范规格型号的规定开展检测。试验室必须矿物质化合物品质的转变。矿物质化合物进到当场后，务必开展用水量，点燃损害和粒度检测。能够储存和纪录检测商品以开展基本检测。较为結果以明确品质起伏并保证新项目品质。

3. Mineral compounds: test according to relevant specifications and models. The laboratory must solve the transformation of mineral compound quality. After mineral compounds enter the site, be sure to carry out water consumption, ignition damage and particle size detection. Be able to store and record tested goods for basic testing. Compare the results to clarify the quality fluctuation and ensure the quality of new projects.

4.减水剂：进到当场时要定期检查检测减水剂。查验混和包裝中的下列新项目。产品名字，型号规格，净或净总数，生产商名字，生产制造时间，加工厂序号。保证包裝信息内容合乎产品型号和生产商的证实，而且液體化合物早已从沉淀中坠落而且早已到期。

4. Water reducing agent: regularly check and detect the water reducing agent when entering the site. Check the following new items in the mixed packaging. Product name, model and specification, net or net total number, manufacturer's name, manufacturing time, processing plant serial number. Ensure that the contents of the packaging information comply with the product model and manufacturer's confirmation, and that the liquid compound has long fallen from the sediment and has long expired.

次之，混泥土的砂浆配合比应恰当。

Secondly, the mortar mix proportion of concrete shall be appropriate.

第三，设备齐全完善的4方自送料混凝土搅拌车称重设备务必精确。

Third, the weighing equipment of the fully equipped 4-party self feeding concrete mixer must be accurate.

4方自送料混凝土搅拌车柴油发动机温度过高

The temperature of diesel engine of 4m3 self feeding concrete mixer is too high

1.4方自送料混凝土搅拌车在一般路面上使发动机过热。它应尽早减少速率，将轿车开到树荫下面，或调到相对性清凉的地区停住轿车，但不必急切歇火。

1.4 the self feeding concrete mixer truck causes the engine to overheat on the general road. It should reduce the speed as soon as possible, drive the car under the shade of trees, or transfer to a relatively cool area to stop the car, but there is no need to stop the fire urgently.

2.开启机盖，让柴油发动机以待速运作，等候柴油发动机溫度慢慢恢复过来。柴油发动机温度恢复过来后，关掉柴油发动机。随后等候一会儿，直柴油发动机的温度充足降低，随后查验柴油发动机的制冷水流量。

2. Open the engine cover and let the diesel engine run at a standby speed, waiting for the temperature of the diesel engine to recover slowly. When the temperature of the diesel engine recovers, turn off the diesel engine. Then wait for a while until the temperature of the diesel engine decreases sufficiently, and then check the cooling water flow of the diesel engine.

4方自送料混凝土搅拌车危害品质的要素和柴油发动机温度过高就这样了，期待对给你协助。

The factors endangering the quality of the 4-party self feeding concrete mixer and the high temperature of the diesel engine are just like this. We look forward to your assistance.
