Quick Start

Video Tutorial Assista o video The Quality Control feature will help you better manage your Readymix Quality inspections. Laboratory Registration To start using Quality Control, we first need to register your laboratory. In summary, the laboratory registration in the system is essential for the management of your samples and inspections, allowing you to have a physical control of where the Readymix inspection was made. Initially, open the menu on the left side of the screen and select "Quality Control">"Laboratory". By clicking on add laboratory you can enter the location of the laboratory, code, name, U.D.M. rupture load, U.D.M resistance, label type and days to collect. Now just fill in the data related to the laboratory: After filling in all the information click on save and close. For more information go to: https://docs.loop4.com.br/hc/docs/articles/1751550477-laboratory Registering the Sample type The second step to use Quality Control is to register in the system the types of samples to be collected. Sample: refers to a Readymix cylinder or block taken from an existing Readymix structure or a newly produced batch to evaluate its compressive strength. To do this, simply open the menu on the left side of the screen and select "Quality Control">"Sample Type". Now click on Add Sample Type and fill in the necessary data: Once finished, click on save and close. For more information, visit: https://docs.loop4.com.br/hc/docs/articles/1751550536-sample-type Defining the type of Inspection The third step is to define the type of inspection to be carried out. Inspection: refers to the process of evaluating and analyzing the properties of Readymix based on the results of the tests carried out on the samples. The inspection aims to obtain information about the quality, integrity and performance of Readymix in a specific structure or lot. To do this, open the menu on the left side of the screen and select "Quality Control">"Type of Inspection". To get started, click Add Inspection Type and fill in the fields with the necessary data and its rules. After filling in the necessary information click Save and Close. For more information go to: https://docs.loop4.com.br/hc/docs/articles/1751550588-inspection-type Creating Inspections As a fourth step we will create the inspection of a sample. Inspection plays a crucial role in ensuring the quality and strength of Readymix. Through it it is possible to determine if the Readymix fits the demand of the final customer, ensuring quality and safety. Stop creating it, open the menu on the left side of the screen and select "Quality Control" > "Inspection". Now click on the "Add Inspection" option to start the addition process. We can create two types of inspection: 1 - Single Inspection - Refers to an occasional evaluation or verification of Readymix samples taken from a specific structure or lot. This single inspection can be carried out outside a predefined schedule and aims to analyze the quality and compliance of the samples with the applicable standards and specifications. 2 - Delivery Inspection - Refers to the systematic verification of Readymix samples at the time they are delivered or subjected to laboratory tests. This delivery inspection aims to ensure that the samples comply with the specifications before being used in resistance tests or other analyses. In this example, I will show you how to do a Delivery Inspection Cline on the "magnifying glass" icon to select the delivery to which these samples belong: When locating the delivery, click on it to mark it and then click "Select". Once this is done, fill in the required fields and click Save and Close. To learn more go to: https://docs.loop4.com.br/hc/docs/articles/1751550643-inspection Breaking Samples As a final step, we will break the sample created. Break Sample: this is the action of subjecting these samples to a load test until the rupture or fracture occurs. The rupture test is crucial to evaluate the quality of Readymix, especially its structural strength. To do this, open the menu on the left side of the screen and select "Quality Control">"Break Samples". On the "Break Samples" screen select the Test Date, Plant, Laboratory and Age (if necessary).

CUSUM Analysis

The CUSUM chart (Cumulative Sum Control Chart) is a statistical tool used to monitor and detect changes in concrete production processes over time. It is based on the accumulated sum of the differences between the observed values and a reference (usually the average expected or objective value) and is often used in quality control. Open the menu on the left side of the screen and select "Quality Control" > "Cusum". Filters The mandatory filters to search for sample data are: - Disruption Period Defines the rupture date of the disruption samples in the system. - Product FCK Define the samples that will be used, for example, the samples in which the product theoretically has the FCK 250. - Factor for FCK 28 days expected Factor used to calculate the FCK measured at 7 days in order to predict the FCK expected at 28 days. - Factor for MTE Factor to calculate the Objective Average Resistance. - Target Range Cusum M Cusum M Objective Range, that is, it is the acceptable range for the analyzes. After setting the filters for the analysis, just click on "Search" and we will have all the sample data in each tab. Sheet In this section, we will have the data in the "Spreadsheet" format, where each column represents a value for analysis. It is also possible to export the data by clicking on the "Export" button. FCK 28 days expected In this section, a graph will be shown that analyzes the projected resistance of the samples at 28 days, based on the results obtained after 7 days of testing. The blue lines represent the Expected Resistance after 28 days. The orange lines represent the Objective Average Resistance that is calculated as follows: Product FCK * Factor for MTE In this example, 250 (FCK Value) * 1.28 (MTE Factor) will be calculated, totaling 320. By hovering the mouse over the blue line, it will be possible to view the expected resistance value after 28 days. And by hovering the mouse over the orange line, it will be possible to view the value of the Average Objective Resistance. Cusum M In this section, a graph representing Cusum M, also known as the Objective Cusum Range, will be shown. Cusum M serves as an indicator that monitors the cumulative variation of concrete resistance results in relation to an established objective or reference value. This acceptable interval for analysis allows you to identify trends or deviations in concrete performance over time. See how this calculation is done in the system: we start by checking the previous value in column "Cusum M" (1) and add to the current value obtained in column "(FCK 28d Esp.) - RMO" (2) and we will have the current value of "Cusum M" (3). Cusum T In this section, a graph representing the Cusum T will be displayed, which reflects the accumulated absolute differences between the values of "FCK 28 expected days" over time, adjusted by subtracting the Average Objective Cusum Time. This indicator allows you to monitor variations and possible instabilities in concrete resistance. How the Cusum T calculation is done: Accumulated of (FCK 28 days expected - FCK 28 days expected previous) - Objective Medium Cusum Time It is also possible to change the value of the Range Cusum M Obj. field and filter it again so that it is recalculated. In this example, we added the value of the Cusum M Obj. Range to 20 and the graph performed the calculations again. Cusum S In this section, a graph representing Cusum S will be shown, which is the cumulative difference between the "FCK 28 Real" and the "FCK 28 days expected". This indicator evaluates the actual performance of concrete in relation to the projected expectation of resistance at 28 days, accumulating deviations over time. How the Cusum S calculation is done: Accumulated FCK 28 Real - FCK 28 days expected See how this calculation is performed in the system: we start by checking the previous value in the column "Cusum S" (1) and subtract the current value obtained in the column "(FCK 28d) - FCK 28d Esp." (2) and we will have the current value of the "Cusum S" (3). Note: All graphs are generated based on the values adopted by the company to perform the analyzes.
