mso-hansi-font-family:"Times New Roman"">砂石漏斗 砂子漏斗 "Times New Roman"">石子漏斗 細集料漏斗 "Times New Roman"">粗集料漏斗
mso-hansi-font-family:"Times New Roman"">一、砂石漏斗說明:
mso-hansi-font-family:"Times New Roman"">砂石漏斗,T0331—1994 "Times New Roman"">細集料堆積密度及緊裝密度試驗砂子漏斗。
mso-hansi-font-family:"Times New Roman"">二、砂石漏斗目的與適用范圍:
mso-hansi-font-family:"Times New Roman"">砂子漏斗測定砂自然狀態(tài)下堆積密度、緊裝密度及空隙率。
mso-hansi-font-family:"Times New Roman"">三、砂石漏斗儀具與材料
1、臺秤:稱量5Kg mso-hansi-font-family:"Times New Roman"">,感量5g "Times New Roman"">。
2、容量筒:金屬制,圓筒形,內(nèi)徑108mm mso-hansi-font-family:"Times New Roman"">,凈高109mm "Times New Roman"">,筒壁厚2mm "Times New Roman"">,筒底厚mm㎜,容積約為1L mso-hansi-font-family:"Times New Roman"">。
3、標(biāo)準(zhǔn)漏斗。
4、烘箱:能控溫在105℃±5℃。
5、其它:小勺、直尺、淺盤等。
mso-hansi-font-family:"Times New Roman"">四、砂石漏斗砂子漏斗試驗準(zhǔn)備:
1、試樣制備:用淺盤裝來樣約5Kg mso-hansi-font-family:"Times New Roman"">,在溫度為105℃±5℃ "Times New Roman"">的烘箱中烘干至恒重,取出并冷卻至室溫,分成大致相等的兩份備用。
mso-hansi-font-family:"Times New Roman""> 注:試樣烘干后如有結(jié)塊,應(yīng)在試驗的先予捏碎。
2、容量筒容積的校正方法:以溫度為20℃±5℃ mso-hansi-font-family:"Times New Roman"">的潔凈水裝滿容量筒,用玻璃板沿筒口滑移,使其緊貼水面,玻璃板與水面之間不得有空隙。擦干筒外壁水分,然后稱量,用式(T0331-1)計算筒的容積V mso-hansi-font-family:"Times New Roman"">。砂子漏斗V=m’2-m’1 (T0331-1)
mso-hansi-font-family:"Times New Roman"">式中:V—— "Times New Roman"">容量筒的容積(mL) "Times New Roman"">;
mso-hansi-font-family:"Times New Roman""> m’1—— "Times New Roman"">容量筒和玻璃板總質(zhì)量(g) "Times New Roman"">;
mso-hansi-font-family:"Times New Roman""> m’2—— "Times New Roman"">容量筒、玻璃板和水總質(zhì)量(g) "Times New Roman"">。
