Witton Cement Group Co., Ltd. Share: cement road range of applications in addition to widely applicable to all types of cement concrete pavement outside road engineering cement, road cement can also be used for other construction projects Witton cement roads, and can get better than the common use of cement effect. In addition to widely applicable to all types of cement concrete pavement engineering, the cement can also be used for other road construction projects, and can get better than common cement results. Witton Cement Group Co., Ltd. Share: Cement major technical indicators (a) gravity and bulk density: standard cement accounted for 3.1 density usually 3100 kg / cubic meter. (2) fineness: Refers to the thickness of the degree of cement particles. Cement road finer particles, the faster hardening, early strength is also higher. (3) Setting time: cement mixing with water to condense the time required to start, said the initial setting time. Add water and stir from time to complete the necessary condensation, said final setting time. Portland cement initial setting time not earlier than 45 minutes, final setting time no later than 6.5 hours. In fact, the initial setting time 1 ~ 3h, and the final setting for 4 to 6 hours. Determination of setting time of cement setting time was measured by a special instrument (4) strength: the strength of cement shall conform to national standards. (5) Volume stability: refers to cement volume change during hardening uniform performance. Cement containing impurities, will produce uneven deformation. (6) heat of hydration: the role of cement and water produces an exothermic reaction in the cement hardening process, continue to heat released is called the heat of hydration. (7) Standard consistency: refers to the standard cement paste consistency test bar sink when a certain resistance.
