Use of ready-mixed concrete plant sludge water in concrete

The use of sludge water in the concrete mix tended to reduce the effect of both fly ash and superplasticizer. Sludge water with a total solids content of less than 6% is suitable for use in the production of concrete with acceptable strength and durability.

Mixing Water Control - National Ready Mixed Concrete Association

Batch water is the water added to the ready mixed concrete truck. Generally this constitutes the primary source of mixing water. Water can be measured by volume using water meters or volumetric tanks; or by weight in scales. ASTM C94 requires that the added water should be accurate to within ±1% of the design total mixing water. Th e

The sustainable use of concrete | K Sakai; Takafumi

What makes this possible is the wide use of concrete as a construction material. Its primary component materials are aggregate, cement, and water, with aggregate constituting approximately 70% of the total volume. The Earth's crust is composed of rocks that are the raw materials for aggregate.

Innovative reuse of concrete slurry waste from ready-mixed

Sludge water from ready-mixed concrete plants as well as dry sludge, which is derived from the settling of the water, are hazardous for disposal due to their high pH value (pH>11.5).

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 ...

Experimental Research on Compressive Strength of Ready

Production cost and emissions of pollutants can be reduced through mixing industry waste, such as mineral powder and fly ash, into ready-mixed concrete. Two approaches are adopted to the experiments to research the effect of mineral powder and fly ash on the compressive strength of ready-mixed concrete: (1) fixing the amount of fly ash, while substituting equivalent amount …

Properties of Retard Type Stabilizing Agent for Reuse of

When we left the sludge water mixed with stabilizing agent, it has been noted that initial retard effect recovered to the level using just service water in 7 ${\~}$ 8 days and that it is effective to use stabilized sludge water in 2 ${\~}$ 3 days. On the other hand, saccharic type super retarding agent was also outstanding in applicability by ...

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 …

Ready-Mixed Concrete Plant: Analysis of Sludge Formed

Ready-Mixed concrete plant operations are large consumers of water. Sludge water is the waste wash water from concrete mixing plants and agitator trucks. Approximately 200 litres of water are used to produce one cubic meter of concrete from a central batch plant. The figure from a truck mix plant is higher, at 300 litres.

Reuse of waste water from ready-mixed concrete plants

Practical implications: Waste water from ready-mixed concrete plants is classified as waste hazardous for disposal due to its high pH value (over 11.5). Very few ready-mixed concrete plants that recycle waste water follow a complicated process through multiple overflows and a …

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 ...
