This document discusses quality control in concrete construction. It explains that concrete is made by mixing cement, fine aggregate, coarse aggregate, water, and admixtures. Quality control is important to ensure the concrete has strength, durability, and aesthetics. Quality control involves testing the materials used, the fresh concrete …

Rising costs of the energy required for its manufacture and the increasing interest in understanding the mechanisms of concrete deterioration, as well as the importance of optimising the use of Portland cement in high quality concrete, have continued to sustain interest in this important material.
The adopted method to assess the quality parameters of Portland cement was 5 tests of cement (compressive strength test, consistency test, fineness test, soundness test, …

Significantly, it was found by Nikhil et al. (2019) that the compressive strength of concrete made using potable water increased by 33.34% compared to concrete made with sewage water [7].
Also, the accuracy may deteriorate due to outliers, noise and missing data [8]. Methods that are traditionally used for soft-sensor model development are: multivariate statistical methods, artificial neural networks and support vector machines [11]. In the production of cement, the quality of the clinker determines the quality of the cement.
interested in the product value, which for cement can be most conveniently expressed as compressive strength in concrete. However, as cement production quality is normally monitored and controlled by most cement producers using cement and sand mixes, the compressive strength referred to hereafter is the mortar strength measured according to

ABSTRACT. The goal of this study is to identify the critical parameters for control of slurry quality during cementing operations.It appears that the cement mixing process can be split into two different processes:–a mechanical one that includes the wetting of the powder, the deflocculation and the homogenisation of the resulting suspension, and–a physico …

The relationship between the burning condition of cement clinker and the ultimate cement properties is well established and being so, determination of burning condition is important in controlling the cement quality. Examination of a large number of cement clinkers from different plants and laboratory clinkers demonstrate that the ratio …
In a good quality cement, the distance should not exceed 10 mm. Autoclave Test Cement paste (of normal consistency) is placed in an autoclave (high-pressure steam vessel) and slowly brought to 2.03 MPa, and then kept there for 3 hours. The change in length of the specimen (after gradually bringing the autoclave to room temperature and pressure ...
