Study on the Influence of Steel Fiber and Basalt Fiber on the Mechanical Properties of Ultra High Performance Concrete (UHPC) with Xuanwu
Ultra high performance concrete (UHPC) was prepared using basalt rock powder, and the effects of steel fiber content (0, 1.
00%, 2.
00%, 3.
00%, 4.
00%, 5.
00%) and basalt fiber content (0, 0.
25%, 0.
50%, 0.
75%, 1.
00%, 1.
25%) on the mechanical properties of UHPC were studied.
The results showed that with the increase of steel fiber content, the 28 day flexural strength and compressive strength of the specimens increased; With the increase of basalt fiber content, the 28 day flexural strength of the specimen significantly improves, while the increase in 28 day compressive strength is relatively small; Under the same dosage, the improvement effect of steel fiber on the mechanical properties of UHPC is better than that of basalt fiber.

C800 concrete: the strongest compressive concrete in the world. How strong is the strongest concrete currently known?!
【 Introduction 】 The strength grade of concrete directly determines the bearing capacity, safety, and applicable scenarios of buildings.
C800 grade concrete is currently known to have the strongest compressive performance in the world in the laboratory.
Its performance breaks through conventional knowledge and is the forefront benchmark of concrete material technology.

This is the most common explanation of “drilled pile” I have ever seen! Top 10 causes+9 tips, recommended for collection
Dear testers, take a few seconds to say something! Previously, I used multiple download methods to share PPT, but the results were not very satisfactory – especially the Baidu Cloud link, which not only frequently failed, but also had to be transmitted from both the website and cloud storage, adding a lot of extra workload.

Literature Sharing 88: Prediction and interpretability of compressive strength of limestone mechanism sand concrete using machine learning
In the field of concrete engineering, the increasing depletion of natural river sand resources has promoted the widespread application of mechanism sand.
Accurately predicting the compressive strength of limestone mechanism sand concrete (MSC) has become a key issue in engineering design and proportioning optimization.
A recent study published in the Journal of Building Engineering, which combines machine learning and microstructure analysis methods, not only constructed a high-precision MSC compressive strength prediction model, but also revealed the regulatory mechanism of key parameters such as stone powder content on its performance, providing important theoretical and practical support for the engineering application of mechanism sand concrete.

Detailed analysis of inorganic grinding stone flooring, creating a lightweight, luxurious, and durable underground garage
The underground garage has never been an ‘insignificant supporting facility’, but an ‘invisible facade’ of project quality, and a key detail that affects homeowners’ repurchase, property reputation, and project premium.
Many high-end real estate projects have impeccable main building and garden landscapes, but the underground parking garage is plagued by issues such as sanding, graying, hollowing, cracking, and difficult to clean stains due to poor floor quality.
This not only greatly reduces the parking experience for homeowners, but also makes it difficult to achieve the high-end positioning of the project.
In the later stage, the property management also needs to invest a lot of manpower and resources in repeated repairs, which is not worth the loss.
