Which Self-Loading Concrete Mixer Can Produce Enough Concrete For 4-5 Story Commercial Buildings In Jakarta Or Surabaya?

In the fast-growing cities of Jakarta and Surabaya, the demand for mid-rise commercial buildings is on the rise. Developers and contractors are looking for efficient, cost-effective ways to produce concrete on-site without depending entirely on ready-mix suppliers. This is where self-loading concrete mixers offer a highly flexible solution. But which mobile self loading concrete mixer can meet the actual concrete needs for 4-5 story commercial buildings? In this article, let’s analyze the real construction scenarios and find the most suitable solution for your projects.

Why Self-Loading Concrete Mixers Are Popular For Mid-Rise Projects

Before selecting the right model, it’s important to understand why many contractors in Indonesia are turning to self-loading mixers for 4-5 story buildings.

First, urban construction sites in Jakarta and Surabaya often face space limitations. Deliveries from stationary batching plants may not always be reliable or timely due to traffic congestion. A self-loading mixer for sale allows contractors to produce concrete directly at the job site, reducing waiting time and transportation costs.

Second, these projects usually involve continuous but not massive concrete pouring. For columns, beams, slabs, and walls of 4-5 story buildings, contractors need steady and flexible daily production rather than large one-time pours. Self-loading mixers are well suited for this steady workload.

Finally, labor cost and operational simplicity are also key concerns. A self-loading mixer integrates multiple functions: loading, mixing, transporting, and discharging. One operator can handle the entire process, which simplifies the workflow and lowers labor expenses.

How Much Concrete Is Actually Needed For 4-5 Story Commercial Buildings?

To choose the right mixer model, we first need to estimate the typical concrete demand on such projects.

Generally, a 4-5 story commercial building with floor areas of 400-600 square meters per floor might require total concrete volumes ranging from 800 m³ to 1500 m³ across the entire construction period. Of course, this varies depending on design, structure, and foundation requirements.

However, concrete is poured in stages. On a daily basis, contractors often need to produce around 20-60 m³ of concrete to support different work sections like columns, beams, slabs, or minor foundations. This daily demand helps us determine the mixer’s ideal production capacity.

Which Self-Loading Mixer Model Matches This Daily Production?

Based on daily production needs of 20-60 m³, the self-loading concrete mixer should have a flexible hourly output while ensuring continuous operation throughout the workday. Let’s analyze a few models:

AS-1.8 Self-Loading Mixer

The AS-1.8 model produces approximately 7-8 m³ per hour. While it’s highly mobile and easy to maneuver on tight sites, its smaller capacity may not fully meet the production demands of larger sections for 4-5 story buildings. It works better for smaller-scale jobs or repair work.

AS-2.6 Self-Loading Mixer

The AS-2.6 model can produce around 10-12 m³ per hour. For small-to-medium sections, this model provides decent output, but if your project has multiple sections being poured simultaneously, its capacity may still feel limited. It may suit smaller crews or projects with lower daily pouring requirements.

AS-3.5 Self-Loading Mixer — The Most Balanced Option

The AS-3.5 is often the ideal choice for 4-5 story commercial building projects. It can mix and discharge approximately 14 m³ of concrete per hour. With continuous operation across an 8-hour workday, it can easily supply 50-100 m³, which comfortably covers the typical daily demands of mid-rise commercial construction.

Moreover, the AS-3.5 features a 3.5 m³ drum volume, which allows larger batch sizes while maintaining excellent mix consistency. Its efficient loading system and powerful engine provide continuous work even in challenging job site conditions.

AS-4.0 Self-Loading Mixer — For Heavier Workloads

If your project involves heavy foundations or simultaneous pours for multiple floors, the AS-4.0 offers an even larger 16 m³/hour output. This ensures high productivity during peak pouring periods. However, for most 4-5 story commercial buildings, the AS-3.5 already strikes the perfect balance between mobility, production, and cost-efficiency.

Other Key Factors To Consider When Selecting The Model

Of course, production capacity is not the only factor. Several other elements influence your decision:

• Site Access: If your site has very narrow access, the slightly smaller AS-3.5 may be easier to maneuver than larger models.

• Labor Force: Smaller crews can fully operate the AS-3.5 without requiring additional support teams.

• Fuel Consumption: The AS-3.5 offers excellent fuel efficiency, keeping operating costs low across the project duration.

• Concrete Quality: All models ensure proper mixing homogeneity, but AS-3.5's larger drum size ensures better consistency for larger pours.

By considering these factors together with daily production needs, many contractors in Indonesia find the AS-3.5 to be the most versatile solution for their commercial building projects.

How Self-Loading Mixers Help You Control Project Timelines

Timely concrete supply is one of the key factors determining whether you can finish each construction phase on schedule. Self-loading mixers eliminate the risks of traffic delays or supplier shortages. They allow you to fully control your pouring schedules and adjust work plans flexibly depending on labor and weather conditions. This control greatly improves project management, reduces downtime, and helps avoid costly schedule overruns.
