What is the Concrete Mix Design Spreadsheet?
The Concrete Mix Design Spreadsheet is a powerful tool that allows civil engineers and construction professionals to design custom concrete mixes based on their specific requirements. With its user-friendly interface and intuitive design, the Concrete Mix Design Spreadsheet makes it easy to create custom mixes that meet your project's needs, whether you're working on a small residential project or a large commercial development.
The spreadsheet is designed to work with the American Concrete Institute (ACI) method of mix design, which is widely recognized as the industry standard for designing concrete mixes. It takes into account a range of factors, including the type and strength of cement, the maximum size of aggregate, and the water-cement ratio, to produce a mix that meets your project's specific requirements.

Flexibility: The spreadsheet allows you to customize your mix design to meet your project's specific needs, ensuring that your concrete will perform as expected in the field.
Cost-effectiveness: By designing custom mixes that meet your project's requirements, you can avoid over-specifying and wasting materials, which can save you money in the long run.
Quick question, what would flain and sizzle look like if they mixed?
Honestly, no ideas. Thought about sketching it out but tbh, I'm not too good at mix design.. I mean, I attempted it with Gloom & M-Nixel but felt like the design wasn't creative or clunky. To be fair, most of the mix design in mixels are either recolored like teslo & zorch or just taking a random body part and attaching it to the dominant mixels (mixels rush). But like we got some banger ones too like looks at these mfs. I don't know how I'm gonna make the mix design look unique as these. (Only have three in my gallery as examples)

What is mix design of concrete?
Mix design of concrete is the process of selecting suitable ingredients like cement, sand, and aggregate with proper proportions relative to each other. It helps to prepare the concrete in an economical way as well as improve the strength, workability, and durability of concrete.
Principles of concrete mix design
The main principle of concrete mix design is to…

This paper presents a focused study on properties of porous concrete to widen its application to structural engineering. Mechanical properties like compressive strength, indirect tensile strength, flexural strength and physical properties like density, permeability and porosity are studied. To determine those parameters, twenty seven cubes, cylinders and prisms were tested. Also, three polymer impregnated porous concrete slabs were tested under pure bending moment to study the efficiency of selected resin to integrate particle of concrete to achieve a new generation in using porous concrete in structural engineering. Three different cement content specimens of porous concrete were considered, studied cement contents are 200 kg m3, 300 kg m3 and 400 kg m3. The results show that, increasing the cement content can increase the compressive strength, indirect tensile strength and flexural strength. Density of porous concrete is less than conventional concrete by 21 but permeability factor recorded higher value compared to conventional concrete by sixteen times. Increasing the cement content has no significant effect on either ultimate load or maximum deflection of polymer impregnated porous concrete slabs but the results recorded an achievement to use this concrete in structural engineering applications and give an easy way to cast special concrete like polymer concrete without special tools.

This civil engineering article is about aggregate and concrete strength. You will learn how course aggregate can impact the mix design of concrete.
Coarse aggregate is considered as one of the vital elements of concrete and captures the major volume in the mix as well as impacts the concrete mix design significantly. Its different characteristics like strength, maximum size, shape, and water absorption affect water demand, the quantity of cement and fine aggregate in concrete mixture.
It is found that high maximum coarse aggregate size can reduce water demand in the mixture as such aggregate contains lower surface area with regards to small coarse aggregate size.
While considering shape, rounded type aggregate offers reasonable mix design for normal strength concrete.
For high strength concrete, angular coarse aggregate is essential. The scope of segregation is reduced when coarser aggregate is graded perfectly for concrete mix design.
While considering strength, greater aggregate strength generates higher concrete strength.
1. Maximum Aggregate Size: The maximum size of coarse aggregate is another vital factor that checks water demand to attain definite workability. It also determines the quantity of fine aggregate content required for developing cohesive mix.
For a specified weight, if the maximum size of aggregate is increased, the surface area of coarse aggregates is reduced and conversely. When the maximum size of coarse aggregate is decreased, the surface area of coarse aggregate is raised. If the surface area is large, the water demand will be increased to coat the particles and produce workability.
For smaller maximum size of coarse aggregate, larger fine aggregate content is required to coat particles and retain cohesiveness of concrete mix. Therefore, for similar workability, 40mm down aggregate contains lower water/cement ratio, thus strength is raised with regards to 20mm down aggregate. Due to its lower water demand, higher maximum size of coarse aggregate can reduce the cement consumption.
Maximum size of aggregate is confined with clear cover and minimum distance among the reinforcement bars. Maximum size of coarse aggregate is lower than clear cover or minimum distance among the reinforcement bars. As a result, the aggregates can get through the reinforcement in congested areas, to form dense and uniform concrete.
2. Grading of Coarse Aggregate: Grading means the establishment of the particle-size distribution for aggregate. It influences the amount of cement and water requirements, workability, pumpability, and stability of concrete. The grading of coarse aggregate is crucial to acquire cohesive and dense concrete. The voids due to larger coarse aggregate particles are filled with smaller coarse aggregate particles.
If the grading of coarse aggregate is perfect, the scope of segregation is reduced, specifically for higher workability and the compatibility of concrete in enhanced. The coarse aggregate grading limits are provided in ASTM C33/ C33M and IS 383 – 1970 – table 2, Clause 4.1 and 4.2 for single size aggregate as well as graded aggregate.
3. Shape of Coarse Aggregate: The shape of coarse aggregates range from round, angular, or irregular. Rounded aggregates contain lowest water demand because of lower surface area, and also contain lowest mortar paste requirement.
These properties facilitate to produce rounded aggregate to give in the most reasonable mixes for concrete grades up to M35. However, for concrete grades of M40 and above the scope of bond failure would slant the balance in support of angular aggregate containing larger surface area.
Flaky and elongated coarse aggregate particles raise the water demand as well as the susceptibility of segregation. The flexural strength of concrete is minimized due to flakiness and elongation. Specifications provided by Ministry of Surface Transport confine the combined flakiness and elongation to 30% by weight of coarse aggregates.
4. Strength of Coarse Aggregate: Material strength of coarse aggregate is determined by crushing strength of rock, aggregate crushing value, aggregate impact value, aggregate abrasion value. The IS limits for above tests range from Aggregate Crushing value, Aggregate Impact value, and Aggregate abrasion value.
5. Aggregate Absorption: The purpose of aggregate absorption is to employ a correction factor for aggregates in dry condition and find out water demand for concrete in saturated surface dry condition. Aggregate can consume water up to 2 % by weight when remains in bone dry state. But occasionally, the aggregate absorption remains as high as 5%.
