水泥漿稠度測定儀
一、概述：水泥是采用硅酸鹽水泥或普通水泥，采用礦渣水泥時，應(yīng)加強(qiáng)檢查，以防止材性不穩(wěn)定。水泥的標(biāo)號不宜低于425號。
水泥漿稠度宜控制在14-18S之間，稠度的測定采用1725ml漏斗試驗，水泥漿稠度測定儀生產(chǎn)廠家規(guī)格質(zhì)優(yōu)水泥漿從漏斗流出的時間（S），即為水泥漿的稠度。水泥漿面位置可用灌入1725ml水的方法找出。用點測規(guī)標(biāo)記。
二、水泥砂漿參數(shù)
灰砂比        砂的種類       水灰比    水泥砂漿容重kg/m2    極限切應(yīng)力pa       粘度 pa.s

                       細(xì)粒河砂          0.91           2080                                 46.0                  0.46
                          粗粒河砂       0.88           2030                                40.6                    0.47
                          中粒河砂       0.83           2000                                44.0                     0.52
       1:1                河砂             1.03            2050                               39.0                    0.59
三、設(shè)備流動錐：出料管應(yīng)用不銹鋼制作，錐體可用鑄鋁或其他非腐蝕性材料制作。
注：只要能獲得水泥（砂）漿漿面的精確值，可以使用其他的指示裝置。接受容器：最小容量為2000ml環(huán)架或其他裝置：保持接受容器上方流動錐位置垂直和穩(wěn)定的裝置。水平尺：木工使用的或類似的水平尺秒表：最小讀數(shù)應(yīng)不大于0.1s。試驗設(shè)備校準(zhǔn)：流動錐應(yīng)以無振動的方式安裝牢固。
