We all hope that the quality of concrete used is very good, but there are many factors that affect the product quality of automatic feeding concrete mixer. What are the factors?

一、原材料質(zhì)量的選擇準(zhǔn)確：

1、 The selection of raw material quality is accurate

1、骨料：粗細(xì)骨料進(jìn)場(chǎng)必須按規(guī)定進(jìn)行抽樣檢驗(yàn)，檢驗(yàn)合格方可使用。粗骨料應(yīng)選用級(jí)配合理、粒形良好、質(zhì)地均勻堅(jiān)固的碎石或碎卵石，粗骨料各種指標(biāo)應(yīng)滿足相關(guān)標(biāo)準(zhǔn)規(guī)范的要求;控制泥含量和泥塊含量，及時(shí)進(jìn)行檢測(cè)，經(jīng)檢驗(yàn)不合格的嚴(yán)禁進(jìn)場(chǎng)卸車。

1. Aggregate: coarse and fine aggregate must be sampled and inspected according to the regulations, and can be used only after passing the inspection. The coarse aggregate shall be gravel or pebble with reasonable gradation, good grain shape and uniform and firm texture, and various indexes of coarse aggregate shall meet the requirements of relevant standards and specifications; the content of mud and clay block shall be controlled, and timely detection shall be carried out. The unqualified ones shall not enter the site for unloading.

2、水泥：水泥進(jìn)場(chǎng)必須按規(guī)定進(jìn)行抽樣檢驗(yàn)，每批進(jìn)場(chǎng)的水泥均要求及時(shí)進(jìn)行標(biāo)準(zhǔn)稠度與溫度測(cè)試，對(duì)質(zhì)量存有懷疑的嚴(yán)禁入倉，并繼續(xù)進(jìn)行其他指標(biāo)測(cè)試，經(jīng)檢驗(yàn)不合格的水泥嚴(yán)禁進(jìn)場(chǎng)。嚴(yán)禁未經(jīng)消解的熱水泥直接使用于工程，對(duì)于已使用的水泥要進(jìn)行追溯，并填制"水泥使用追溯表"。

2. Cement: sampling inspection must be carried out for cement entering the site according to the regulations. Standard consistency and temperature test shall be carried out for each batch of cement entering the site in time. If there is any doubt about the quality, it is forbidden to enter the warehouse, and other index tests shall be continued. The cement that fails to pass the inspection is not allowed to enter the site. It is strictly forbidden to directly use the non digested hot cement in the project. The used cement should be traced and the "cement use traceability table" should be filled in.

3、礦物外摻料:根據(jù)有關(guān)標(biāo)準(zhǔn)規(guī)范的要求進(jìn)行檢測(cè)。試驗(yàn)室應(yīng)隨時(shí)掌握礦物外摻料的質(zhì)量變化情況，礦物摻料進(jìn)場(chǎng)時(shí)，必須進(jìn)行需水量比、燒失量、細(xì)度檢測(cè)，經(jīng)檢驗(yàn)合格的產(chǎn)品方可入庫;并注意與前期試驗(yàn)結(jié)果進(jìn)行對(duì)比，以判定質(zhì)量的波動(dòng)情況，確保工程質(zhì)量。

3. Mineral admixture: according to the requirements of relevant standards and specifications for testing. The laboratory should master the quality changes of mineral admixtures at any time. When mineral admixtures enter the site, water demand ratio, loss on ignition and fineness test must be carried out, and the qualified products can be put into the warehouse; and the comparison with the previous test results should be paid attention to determine the quality fluctuation and ensure the engineering quality.

4、外加劑:外加劑進(jìn)場(chǎng)時(shí)應(yīng)加強(qiáng)檢查、檢測(cè)，檢查外加劑的包裝上是否在明顯位置上注明以下內(nèi)容：產(chǎn)品名稱、型號(hào)、凈含量或體積、生產(chǎn)廠名、生產(chǎn)日期及出廠編號(hào);檢查包裝物所標(biāo)明的內(nèi)容是否與生產(chǎn)廠家提供的產(chǎn)品說明書、合格證相符;液體外加劑是否析出沉淀物，是否超過有效期。

4. Admixtures: when admixtures enter the site, inspection and testing shall be strengthened to check whether the following contents are indicated on the package of admixtures at obvious positions: product name, model, net content or volume, name of manufacturer, date of production and factory number; whether the contents marked on the package are consistent with the product manual and certificate provided by the manufacturer; Whether the liquid admixture precipitates precipitates and whether it exceeds the validity period.

二、混凝土的配合比要正確。

2、 The mix proportion of concrete should be correct.

三、攪拌站中的稱量系統(tǒng)要精確。

3、 The weighing system in the mixing plant should be accurate.

影響自動(dòng)上料混凝土攪拌車的產(chǎn)品質(zhì)量的因素有很多，我們應(yīng)該多多注意。

There are many factors that affect the product quality of automatic loading concrete mixer, we should pay more attention to it.
