Mix Design Mix design mainly depends on the strength required & quality of material available. The main ingredients in manufacturing solid concrete blocks are: 1) Cement 2) Fly ash 3) Crushed sand (0-3mm) 4) Aggregates (5-10mm) Typical mix design for solid concrete blocks is given below, Mix design for block grade –7.5 Mpa (target strength)
This study is based on the observation that the river sand commonly used in ordinary and high-performance concrete is becoming increasingly scarce [1,2,3,4,5,6].Manufactured or recycled alternatives exist and one of the solutions to overcome this issue is a partial or total substitution of the river sand in concrete mix-design.
4.1 Fresh concrete properties. Fresh concrete or plastic concrete is a freshly mixed material which can be moulded into any shape. The workability (Fresh concrete test) test results carried out by using slump, compaction factor, flow and vee bee degree with different percentage replacement of natural sand by manufactured sand and 20% cement replaced …
For a severe freeze-thaw exposure, Table 9-5 recommends a target air content of 6.0% for a 25-mm aggregate. Therefore, design the mix for 5% to 8% air and use 8% (or the maximum …

In recent years, manufactured sand has been progressively used to replace natural sand in building materials [1]. This new type of material, produced by crushing rock depositions, exhibits some ...
earlier title 'Recommendedguidelines for concrete mix design'. b) The applicability ofthe standard has been specified for ordinary and standard concrete grades only. c) Various requirements have been modified in line with the requirements of IS 456 : 2000 'Plain and reinforced concrete - Code ofpractice (fourth revision)'.
Abstract. Mix design, which means selecting the appropriate proportion of different components in concrete materials, is the initially important step to access the optimal …
This study investigates the impact of self-compacting concrete (SCC) with manufactured sand (M-sand) on improving the flexural behaviour of reinforced concrete (RC) beams. M-sand is finely crushed aggregate sourced from rocks or quarry stones, providing a sustainable substitute for natural river sand in construction. It ensures uniform quality, cost …

The ordinary Portland cement was partially replaced with silica fume by 5%, 7%, 10%, 12%, 14% and 15%. Natural sand was replaced with manufactured sand by five proportions (i.e. 10%, 25%, 50%, 75% and ). Concrete mix has been designed for grade M40 as per IS 10262 – …
This paper presents a study on the working performance and rheological properties of manufactured sand wet shotcrete (MSWS). Samples with different unit water consumption, water to cement ratio, sand ratio, and water reducer dosage were tested for slump, inverted slump cone flow time, and rheological parameters. The test results were analyzed …
This article describes in detail the procedure to Concrete Mix Design by ACI followed by an example. Let us start with the basics of mix design. What is Concrete Mix Design? Simply put, the concrete mix design means to find the types of materials to be used in the concrete mix in addition to their quantities.. If you have previous data on a certain mixture …
Efforts have been made in the concrete industry to use e-waste plastics as a partial replacement of the coarse or fine aggregates. The present study is focused on replacing conventional coarse aggregate ranging from 0 to 12.5% with e-waste plastic for M 20 grade concrete using manufacturing sand.
This method takes into consideration the requirements for consistency, workability, strength and durability. This article presents ACI method of concrete mix design. ACI Method of Concrete Mix Design Required Data: Before starting concrete mix design, basic information on raw materials shall be prepared which include:

Retempering is defined as, "Addition of water and remixing of concrete or mortar which has lost enough workability to become unplaceable". Retempering inevitably results in some loss of strength compared with the original concrete [1]. Adding water to a plastic mix to increase slump is an extremely common practice, even though it is not recommended because …

Nevertheless, studies have shown that using manufactured sand with appropriate stone powder content can improve the workability and compactness of concrete, enhancing its cracking resistance [[25], [26], [27]]. Menadi et al. [28] tested the mechanical properties of a concrete made using dust and manufactured sand (as a replacement to river …
In this study, ordinary Portland cement was replaced with different industrial by-products such as ground-granulated blast-furnace slag (GGBFS) and microfine (MF) with a fraction of 0%, 10%, 20%, 30%, 40%, 50%, and 5%, 10%, 15%, and 20%, respectively, and tested at the ages of 7, 28, 56, 90, and 180 days after water curing.
