Daftar Isi:
- Retarding admixtures or retardes are used in the mixing concrete to prolong the setting time or the plasticity of fresh concrete. This is normally done to avoid complications when unavoidable delay may occur between mixing and placing. Moreover, prolonging the setting time or the plasticity of fresh concrete is benefit in placing mass concrete or when the weather is quite hot that normally occurs in Indonesia. A retarder is also used to avoid a cold joint between previously poured concrete that is already hardened and new fresh concrete. This paper reports the effect of cane sugar on the setting time of cement paste using the standard Vicat apparatus to see how effective is the sugar cane can be used as a retarding ctchnixure. In the experiment cement paste was blended with various amount of cane sugar produced by Madukismo, Yogyakarta, Indonesia. The amount of cane sugar varies from 0 % to 0.20 % of the used cement in weight. The test results showed that cane sugar can be used as a retarding admixture. This is because the use of the cane sugar caused the delay of the setting time. For the various amount of sugar ranging from 0 % to 0.20 %, the setting time was increased from 2 hours to almost 18 hours.
