In this study, we investigated the feasibility of using sludge water from a ready-mixed concrete plant as mixing water in concrete containing either fly ash as an additive or a superplasticizer admixture based on sulfonated naphthalene-formaldehyde condensates (SNF). The chemical and physical properties of the sludge water and the dry sludge ...

What Is The Proper Method For Concrete Slurry Disposal?

However, the devastating effects of leaving concrete slurry exposed and neglected by contractors are universal. First, when the concrete slurry is allowed to run down pipes, they erode the pipes quicker while creating a water blockage or a flood. Second, if the concrete slurry runs into the storm drain, it will negatively affect the ocean ...

Test Machinery System of the Pressure Water Absorption

Concrete is a composite construction material composed primarily of aggregate, cement, and water. While different formulations provided varied properties. Some times engineering structure need to expand its span length, the commonly thinking is how to decrease the dead load by no harming the structure capacity. The lightweight aggregate concrete focus on the light weight of …

Water-to-Cement Ratio and Aggregate Moisture Corrections

Whether you are using your own batch plant with automated moisture probes or purchasing ready-mixed concrete, it is extremely important that all individuals involved with the batching, mixing and casting of concrete understand the importance of maintaining the specified water-to-cement ratio.

Soil Investigation

Obviously, to be useful, readymixed concrete must be available within a reasonable distance from the project. On remote sites and sites requiring large quantities of concrete, generally field concrete batch plants are used. Concrete purchased from a ready-mixed concrete plant can be provided in several ways. These include : a)
